The distributions of ages at which words are produced are shown in the figures below. The first figure plots the empirical age distributions of the data collected by by Liu & Tsao (2010). The second figure plots the model-based estimates of the words' age of acquisition.
下圖為696個華語詞彙產出的年齡分配。這些分配是根據 Liu 與 Tsao (2010) 所收集之 MCDI 資料並透過模型估計而得。原始資料來源為 Wordbank 專案 (Frank 等，2017): https://github.com/langcog/wordbank。
Liu & Tsao (2010)'s data is available from the Wordbank project (Frank et al., 2017) at https://wordbank.stanford.edu/data/.
Raw data can be found in raw/, and the age distribution data is available in made/MCDI.age-production.csv. The model-based estimates are found in made/MCDI.age.m-produciton.csv, and the code for fitting the model is found in model_based_analysis.R and model.stan.
