Description
Discrete factor analysis with the truncated Poisson distribution
Usage
dfpt(y, A = NULL)
Value
A list with entries
AIC
AIC value for the optimal model
indexmat
Factors and variables in each factor
estlambda
Estimated parameters for factors
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.
