I would like to do the Multiple Correspondence Analysis, but when I use the "< mca(lf, nf = 2, abbrev = FALSE)", the sentence "Error: couldn't find function 'mca'" will appear. So, please tell me how can I use the "mca()", thanks! Any help appreciated....

...this PMF, I decided to specify a maximum value as imax instead of infinity without loss of any information, and n is the binomial trials.
