Latent Variable Interpretation / Derivation
A latent variable model involving a binomial observed variable Y can be constructed such that Y is related to the latent variable Y* via
The latent variable Y* is then related to a set of regression variables X by the model
This results in a binomial regression model.
The variance of ϵ can not be identified and when it is not of interest is often assumed to be equal to one. If ϵ is normally distributed, then a probit is the appropriate model and if ϵ is log-Weibull distributed, then a logit is appropriate. If ϵ is uniformly distributed, then a linear probability model is appropriate.

Famous quotes containing the words latent and/or variable:
“Perhaps having built a barricade when you’re sixteen provides you with a sort of safety rail. If you’ve once taken part in building one, even inadvertently, doesn’t its usually latent image reappear like a warning signal whenever you’re tempted to join the police, or support any manifestation of Law and Order?”
—Jean Genet (1910–1986)
“There is not so variable a thing in nature as a lady’s head-dress.”
—Joseph Addison (1672–1719)
