Comment(by josefpktd):

 This is what the test is supposed to do, I don't think we have this test
 in scipy.stats
 sample variance on top (check ddof of variance, not that it matters at
 large sample sized)

 http://en.wikipedia.org/wiki/Chi-squared_test#Chi-
 squared_test_for_variance_in_a_normal_population
 http://en.wikipedia.org/wiki/Variance#Distribution_of_the_sample_variance

 I think the distribution should be correct also for large samples if the
 distribution is not normal, (central limit theorem?).
