dfnbt: Discrete factor analysis for the truncated negative binomial distribution (with right truncation at A)
Description
Discrete factor analysis for the truncated negative binomial distribution (with right truncation at A)
Usage
dfnbt(y, A)
Value
A list with entries
AIC
AIC value for the optimal model
indexmat
Factors and variables in each factor
estr0
Estimated value of r for the factor
estp0
Estimated value of p for the factor
estr
Estimated value of r for the observation
estp
Estimated value of r for the observation
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.
