This study aimed to vertically scale the mathematics and Japanese academic ability tests of the Japan Child Panel Survey (JCPS) for elementary school first year students through junior high school third year students (grades 1-9 in the U.S.). We used an anchoring test design based on the item response theory. Two test samples were used: JCPS test participants (n = 3,916) and anchoring test participants (n = 7,210). After estimating the item parameters with a two-parameter logistic item response model, the equating coefficients were estimated with the Haebara method. The tests were scaled for elementary school fifth year (grade 5) in the end. The number of items included in the final analyses was 94 for mathematics and 108 for Japanese language studies. The mean level of estimated individual latent academic ability progressed according to grade level. Therefore, the JCPS tests appear to be able to capture the developmental changes of students from elementary school to junior high school. Future research should examine the relationship between children’s academic development and various factors, such as psychological traits or family environment, using the JCPS research data.

既存のレコメンデーションシステムの問題点として、消費者に既知の情報を提示してしまうことや情報収集行動での閲覧内容と実際に購入したい内容が同一ではないことを無視した学習と提示を行う可能性があることにある。本研究では統計的機械学習のモデルに行動経済学的な知見を導入することでこの問題を回避するレコメンデーションシステムを開発し、中古車自動車情報提供サイトの大規模データに適用した解析例を報告する。

The purpose of this study is to demonstrate that process simulation can improve the prediction accuracy of marketing research. First, we argue that photo-simulation-manipulation, proposed by Takeuchi (2015), is based on process simulation. Considering this argument, we conduct a randomized experiment in which participants are assigned to three groups (photo-simulation-manipulation vs. how-manipulation vs. non-manipulation). The participants answer the mind-set manipulation task based on the condition assigned to them and conjoint measurement in the main experiment. In addition, we investigate the products that the participants actually purchased in a follow-up survey. We find that in contrast to non-manipulation, photo-simulation-manipulation improves the prediction accuracy of participants' purchase deduced from conjoint measurement. We discuss the reason for this result and conclude that the participant responses better reflect actual purchase behavior due to activation of memory of past purchases and association with the target products caused by process simulation.

Research has shown that personality traits have strong predictive validity for economic variables (e.g., income, work attainment) and epidemiological variables (e.g., longevity, physical health), as well as for psychological variables such as problem behaviors, and mental disorders. Importantly, personality traits are predictive even after controlling for socioeconomic status and cognitive abilities. The authors believe that current personality research in Japan almost completely overlooks this perspective. In this article, the authors review these new trends in personality psychological research. They propose a model for research involving A (accurate assessments), B (big samples), C (controlling for covariates and confounders), D (developmental trajectories), and E (economic and epidemiological variables). They outline three future directions to embody personality psychology for prediction, prevention, public wealth, and population health.

In this paper we surveyed several fit indices, model modification methods, and other related previous studies in structural equation modeling. Inconsistency in results was detected from the review of the literature. To obtain more reliable knowledge, we performed simulation studies some ten times larger in scale than previous studies to examine the soundness of Golden Rules and the relationship between indices. Also, bias in the distribution of likelihood ratio statistics which depends both sample size and model complexty was indicated as a result of another large simulation study. This could be one of the causes of inconsistency in former studies of fit indices. We also examined fit indices for structural equation modeling with mean structure, multiple groups and categorical indicators. Stepwise estimation methods, model modification methods, and Item Parceling Issues were also reviewed.

We propose a propensity score weighted M-estimation method for marginal parametric models for groups in which all subjects are missing. It is shown that the propose estimator is consistent and its limiting distribution is normal. We also propose a hypothetsis testing method using the proposed estimator. Using the proposed method, we estimate the intervention effect of maternal smoking during pregnancy on the development of the child's cognitive functioning from data obtained from the US National Longitudinal Survey of Children and Youth.

日本を含めて多くの国で多様化や競争、成果に対するアカウンタビリティを重視するガバナンス改革が行われてきた。また同時に、単なる知識や技能の習得からそれらを活用する力や課題解決力、コミュニケーション能力などの育成に向けた教育の質の転換の必要性に関する議論が展開されてきた。本研究の目的はガバナンス改革と教育の質保証との関係を検討しようとするものであり、成果志向の改革では、広い能力概念に基づく教育において評価がどこまでまたどのように用いられるのかが重要な課題となってきていることなどを示した。

We propose an econometric two-stage model for category-level purchase and brand-level purchase which allows simultaneous brand purchase at the same time. The proposed model formulation is consistent with the traditional theory of consumer behavior, and the utility functions remain to be normally distributed. Such modeling approaches have not been found in existing econometric models. The simulation studies show the previously proposed related models can cause severe bias in predicting the future brand choices, while the proposed method can effectively predict them. Additionally in real data analysis, while the existing methods provided the parameter estimation results that were implausible, the proposed method provided the results that were plausible.

Nowadays, along with the popularity of E-Commerce, the marketing strategy of retail stores has been more complicated with O2O or Omni-channel. Therefore, Customer Relationship Management (CRM) is one of the important issue for the retail stores. It can be difficult to predict customers future behavior with the simple quantitive information such as purchase frequency since each customers are widely diversified. Although the company can obtain the variety of customers information from their online activity, the use of access history is still limited. In this paper, we defined “the variety of user access patterns” collected from their web browsing history and it shows the patterns they visit the website. Finally, we verified its effectiveness with developing a DNN model to predict customers future behavior.

In behavioral sciences, it is often difficult to execute an experimental study with random assignment. Therefore researchers usually do a quasi-experiment or a survey study without random assignment. However, under these studies the distributions of the covariates that would affect dependent variables usually differ with the values of the independent variables. To eliminate the influence of the covariates, various adjustment methods such as analysis of covariance have been applied to these data. Recently new adjustment methods using the propensity score proposed by Rosenbaum & Rubin (1983) have been applied to many researches especially in the areas of medicine or economics, and these methods also attract attention in behavioral sciences. The propensity score methods are also used for adjustment of survey data. In this paper, we give a detailed explanation of several estimation methods of causal effect using the propensity scores and related topics. We also review adjustment methods of biased survey data using the propensity scores.

We showed that the propensity score weighted M-estimation method proposed by Hoshino (2005) can be applied in order to adjust for the bias in sampling surveys for marketing research. Further, using real data sets, we investigated the capabilities and the limitations of the propensity score adjustment method to the adjustment of the biased internet surveys and demonstrated the validity of Hoshino's method. By using the covariates selected the method proposed by Hoshino and Maeda (2006) in two similar surveys, we found that the effectiveness of the adjustment method using the propensity scores was reproducible.

Psychological research often deals with psychological constructs that cannot be directly measured. Thus independent variables of regression analysis for an observable dependent variable are sometimes latent variables (factors) that are defined independently of the dependent variable. In this study we pointed out the problem associated with the use of factor analysis for the combined set of dependent variable and independent variables in such a cases; that is, the derived factors are different from those originally intended, and the true regression parameters cannot be reproduced. We proposed a stagewise estimation method to solve the problem. This method estimates parameters of measurement equation in the first stage, and then estimates parameters of structural equation in the second stage. Our proposed method enables calculation of standard errors of estimators using Bootstrapping method. Numerical studies showed that the proposed method improves the estimation efficiency over the conventional methods, and provides estimates which are robust with respect to misspecification of model.

<p>値引きとポイント付与とでは,どちらのセールス・プロモーションの効果が大きいのであろうか。本研究では,食品スーパーにおける集計された購買履歴データを用いて,ポイント付与に関するプロモーション弾力性および値引きの弾力性の推定をおこない,両者の効果の比較をおこなった。プロモーション弾性値の測定の結果,ベネフィット水準が高くなるほど値引きの弾性値が高くなる一方,ポイント付与の弾性値は低くなる傾向が確認された。これらの結果,商品単価が低く値引率・ポイント付与率も低いときには,ポイント付与の方が値引きよりも売上効果が高くなることが確認された。小売業が低いベネフィット水準においてプロモーションをおこなう場合には,値引きよりもポイント付与の方が有利であることが示唆される。</p>
