Parameters

mean1

Type: SystemDouble

var1

Type: SystemDouble
The first sample's variance.

samples1

Type: SystemInt32
The number of observations in the first sample.

mean2

Type: SystemDouble
The second sample's mean.

var2

Type: SystemDouble
The second sample's variance.

samples2

Type: SystemInt32
