Abstract:
|
Latent class model is widely used in social science to classify the similar objects into groups. But the number of classes is key in the latent class model. The arising question is how many classes exist given the data. Determination of number of classes is important but difficult. Several measures of goodness-of-fit are proposed to determine the number of classes. We compare the performance of these measures under latent class models.
