The LCA_Distal Stata functions estimate the association between a latent class variable and a distal outcome. Both functions require the LCA Stata plugin (version 1.2.1 or higher) and Stata (version 9.1 or higher).

NOTE: We recommend using the LCA_Distal_BCH function and offer the LCA_Distal_LTB function only for methodological research.

Features of the LCA_Distal_BCH function

  • requires simple, minimal syntax
  • estimates class-specific probabilities and standard errors for binary and categorical distal outcomes
  • estimates means and standard errors for count and continuous distal outcomes
  • accommodates distal outcomes for multiple groups
