multpois: Analyze Nominal Response Data with the Multinomial-Poisson Trick
Dichotomous responses having two categories can be analyzed
with stats::glm() or lme4::glmer() using the family=binomial option.
Unfortunately, polytomous responses with three or more unordered
categories cannot be analyzed similarly because there is no analogous
family=multinomial option. For between-subjects data,
nnet::multinom() can address this need, but it cannot handle random
factors and therefore cannot handle repeated measures. To address this
gap, we implement the multinomial-Poisson trick (Baker 1994) <doi:10.2307/2348134>,
which transforms nominal response data into counts for each categorical
alternative. These counts are then analyzed using (mixed) Poisson regression.
Omnibus analyses of variance can be run along with post hoc pairwise
comparisons. For users wishing to analyze nominal responses from surveys
or experiments, the functions in this package essentially act as though
stats::glm() or lme4::glmer() had a family=multinomial option.
