# InvT_Dist

Advanced Analysis Library Only

AnalysisLibErrType InvT_Dist (double probabilityT, int degreesOfFreedom, double *t);

## Purpose

Calculates t, given a probability (0 < p < 1), such that:

prob(T < t) = p

where T is a random variable from a T-distribution with the specified degrees of freedom

### Example

double p, t;
int n;
p = 0.635;
n = 2;
InvT_Dist (p, n, &t);

## Parameters

Input
Name | Type | Description
probabilityT | double-precision | Input probability value (0 < p < 1).
degreesOfFreedom | integer | Degrees of freedom for the T-distribution.
Output
Name | Type | Description
t | double-precision | The unique number t such that prob(T < t) = p where T is a random variable from a T-distribution with the specified degrees of freedom.

## Return Value

Name | Type | Description
status | AnalysisLibErrType | A value that specifies the type of error that occurred. Refer to analysis.h for definitions of these constants.
