# lnreChi2: multivariate chi-squared test

`lnreChi2 (-h -mZ) textxX.spc`

A multivariate chi-squared test for evaluating goodness of fit.

input

`text_xX.spc:` expected frequency spectrum at N_0

`text_xX.sp2:` expected spectrum at 2N_0

`text_xX.ev2:` expected vocabulary size at N_0 and 2N_0

options

`-h:` display on-line help

`-mZ:` use the first m ranks only (default: use all m in X.spc)

output

`text_xX.chi:` goodness-of-fit statistics

`text_xX.cov:` the covariance matrix
