Normal Distribution
Another name for a Gaussian Distribution. Given a normal distribution in a Variate 
with Mean
and Variance 
,
the so-called ``Standard Normal Distribution'' is given by taking
and 
. An arbitrary normaldistribution can be converted to a Standard Normal Distribution by changing variables to 
, so
, yielding
The Fisher-Behrens Problem is the determination of a test for the equality of Means for two normaldistributions with different Variances.See also Fisher-Behrens Problem, Gaussian Distribution, Half-Normal Distribution, Kolmogorov-SmirnovTest, Normal Distribution Function, Standard Normal Distribution, Tetrachoric Function
