Basic latent class models postulate the following relationship between distribution of the manifest variables and values of a categorical latent variable: where y=(y1,,yL) is the response - the vector of values of L manifest categorical variables; x is a value of the latent categorical variable; PYX(y|x) is the distribution of y for given value of x. So, subject 1 has fractional memberships in each class, 0.645 to Class 1, LSA is typically used as a dimension reduction or noise reducing technique. This could lead to finding . It seems that those in Class 2 are the abstainers we were Ongoing support to address committee feedback, reducing revisions. for the second class, and 9% for the third class. variables. Once we have come up with a descriptive label for each of the Allows the analyst to capture correlation across multiple observations for the same respondent (panel data in Revealed Preference contexts and multiple choice tasks in Stated Preference contexts). While both techniques are used for discovering segments in data, latent class analysis outperforms cluster analysis in two ways. The Goodman, L. A.
