Normality math
WebThe condition of normality of the residuals is useful when residuals are also homoskedastic. The result is then that OLS has the smallest variance between all of the estimator (linear OR non-linear). The extended OLS assumptions: E ( u X i = x) = 0. ( X i, Y i), i = 1, …, n, are i.i.d. Large outliers are rare. WebThe following equation is used for calculating acid and base molarity where the concentration is given in wt %: [ (% × d) / MW] × 10 = Molarity. Where: % = Weight …

This function tests the null hypothesis that a sample comes from a normal distribution. It is based on D’Agostino and Pearson’s [1], [2] test that combines skew and kurtosis to produce an omnibus test of normality. The array containing the sample to be tested.
