I have a question about possibility of adding Variance test (1-Variance, 2-Variances Levene's test) and Propotion test.

Thank you.

so normally a levene's test is used when testing assumptions for an existing analysis, so we do include this in a few places (for example, in the independent samples t-test).

if you look under the frequency menu, you'll find our proportion tests; binomial, and goodness of fit.

is that what you're after?

Improvement suggestion:

In contingency tables results for a 2x2 table, in addition to the logOR, OR and RR, I also would like to see the absolute difference in proportions and 95%CI as reported in prop.test.
The inverse of the absolute difference is the number needed to treat, used to assess the potential impact of interventions.
