MicroStrategy ONE
Paired T-test, two-sample (for means)
Calculates the P-value of a T-test on the means of two paired sets of data. Two-sample analyses are used to determine the level of variance between the means of paired samples.

Definition
P-value is basically a probability of making a Type 2 error.
PairedTTest
returns the P-value for the hypothesis test in the following form:
-
H0:
-
H1:
Syntax
PairedTTest <Type, Offset> (
Argument1
,
Argument2
)
Where:
Argument1
is a fact or metric representing a set of sample values.
Argument2
is a fact or metric representing a set of sample values.
Type
is a logical value that determines the form of the function.
Usage Notes
One of the results of this sample is pooled variance, an accumulated measure of spread data about the mean. Pooled variance is calculated as:
