Chi square test for variance
Hi all,
in Prime Inference App we have to tests for Chi2 (chi square): Goodness of Fit and 2-way-test... However I need to calc chi2 test having only s^2 and σ^2 (H_0: σ^2 = value, H_1: σ^2 ≠ value) (i.e. s^2 = 0.0153, σ^2 = 0.01, n=20) the test to confront with chi-square should be \[ X_{0}^{2}= \frac{(n-1)s^{2}}{σ_{0}^{2}} \] (for my data I should have X^2= 29.07 against chi-square(19,1-0.05)=30.14 and then reject H_0)... Can I do something already with Inference app? If not I hope to see also this test Chi2 for variance added in Inference App (chi2 test section) in a next upgrade of the firmware... :-) Thank you Salvo ∫aL√0mic (IT9CLU) :: HP Prime 50g 41CX 71b 42s 39s 35s 12C 15C - DM42, DM41X - WP34s Prime Soft.
