GTEST: Single sample Geary goodness-of-fit hypothesis test.

H=GTEST(X, alpha) performs the Geary Test by G. Levin to determine whether the null hypothesis of composite normality PDF is a reasonable assumption regarding the population distribution of a random sample X with the desired significance level alpha.

H=0 => Reject the null hypothesis at significance level ALPHA.

Alternative Hypothesis: X is not normal.

The test evaluates the "good estimator of STD(X) for normal distribution"/"reasonable

estimator of STD(X)" ratio. If X taken from a non-normal distribution this ratio is considerably different from 1. 0.

The decision to reject the null hypothesis is taken when the P value is less than significance level ALPHA.

X must be a row vector representing a random sample. ALPHA must be a scalar.

The function doesn't check the formats of X and ALPHA, as well as a number of the input and output parameters.

H=GTEST(X, alpha) performs the Geary Test by G. Levin to determine whether the null hypothesis of composite normality PDF is a reasonable assumption regarding the population distribution of a random sample X with the desired significance level alpha.

**H indicates the result of the hypothesis test according to the MATLAB rules of conditional statements:**

H=1 => Do not reject the null hypothesis at significance level ALPHA.H=0 => Reject the null hypothesis at significance level ALPHA.

**The Geary's hypotheses and test statistic are:**

Null Hypothesis: X is normal with unknown mean and variance.Alternative Hypothesis: X is not normal.

The test evaluates the "good estimator of STD(X) for normal distribution"/"reasonable

estimator of STD(X)" ratio. If X taken from a non-normal distribution this ratio is considerably different from 1. 0.

The decision to reject the null hypothesis is taken when the P value is less than significance level ALPHA.
