dfzipt: Discrete factor analysis with the truncated zero inflated Poisson distribution
Description
Discrete factor analysis with the truncated zero inflated Poisson distribution
Usage
dfzipt(y, A = NULL)
Value
A list with entries
AIC
AIC value for the optimal model
indexmat
Factors and variables in each factor
estpilam
Estimated zero-inflated parameters for for each factor
estlam
Estimated parameters for each factor
estpimu
Estimated zero-inflated parameters for each variable within each factor
estmu
Estimated parameters for each variable within each factor
Arguments
y
Data, an n by d numeric matrix
A
truncation point (Note that if the data is in Likert scale
starting from 1, then you should subtract 1 from the data and then use the
proposed negative binomial models.
