[Corpora-List] Statistical tests for corpus studies

[Rayson, Paul]

Dear Josephine,

I would recommend the log-likelihood statistic over chi-squared as it is applicable to a wider range of frequencies. For more details see:

Dear all,

As a lay-man to statistics, I wish to get some advice on the tests suitable 
for comparing the frequency of a specific type of word in corpora of 
different genre. Having in mind are Chi-square and ANOVA but I'm not sure 
they are the appropriate ones.

Thanks in advance
