Language change is represented on a graph as a "slow-quick-quick-slow" S-curve. Fitting an S-curve model, language change data can be expected to summarize and analyse past trends and to predict future trends. This study discusses Piotrowski-Altmann's model and a model using a logistic curve, which are the major ones employed in the limited number of S-curve studies. We also discuss cases - a study of honorifics in Okazaki city, the standardization of modern Japanese in Tsuruoka city, and Chinese character words spreading in 19th and 20th century Japanese - which employ a multiple logistic regression with a multifactor approach. The requirements of an S-curve model for a study of language change are considered.
