We carry a huge amount of good quality reference materials on subjects varying from equations in two variables to polynomial Definition 1: For any coefficient b the Wald statistic is given by the formula. Wald = b/se b. Observation: Since the Wald statistic is approximately normal, by Theorem 1 of Chi-Square Distribution, Wald 2 is approximately chi-square, and, in fact, Wald 2 ~ χ 2 (df) where df = k - k 0 and k = the number of parameters (i.e. the number of coefficients) in the full model and k 0 = the number. Test Statistic: $$T = (N-1)(s/\sigma_0)^2$$ where N is the sample size and s is the sample standard deviation. The key element of this formula is the ratio s/σ 0 which compares the ratio of the sample standard deviation to the target standard deviation. The more this ratio deviates from 1, the more likely we are to reject the null hypothesis

h = ttest2(x,y) returns a test decision for the null hypothesis that the data in vectors x and y comes from independent random samples from normal distributions with equal means and equal but unknown variances, using the two-sample t-test.The alternative hypothesis is that the data in x and y comes from populations with unequal means. The result h is 1 if the test rejects the null hypothesis. Matrix Calculator Matrix Calculator computes all the important aspects of a matrix: determinant, inverse, trace , norm.
