Description Usage Arguments Value Examples
This function is used to estimate theta and psi in multinomial mixture model given the number of components k.
1 |
data |
- data in matrix formation with n rows and p columns |
d |
- number of categories for each variable |
k |
- number of components |
TT |
- number of iterations in Gibbs sampler, default value is 1000. T should be an even number for 'burn-in'. |
theta - vector of probability for each component
psi - specific probability for each variable in each component
