This fuction uses the "variance ratio test" and the "rkp" associated functions to compute the variance ratio ,the tests statistics and the corresponding p-values based on randomization (simulation).


Platforms: Matlab

Besides the power estimation it makes the hypothesis testing concerning the one-sample variance. The function only needs the sample variance, the sample size, the hypothesized value and the significance level.

I designed this function with the clear intention in mind of constructing a (useful) database of refractive index. This is basically a function to organize things and (hopefully) set an standard.The function computes the refractive index using a standard form of the Sellmeier formula (as the ones...
