{{alias}}( x, v )
|
|
Evaluates the cumulative distribution function (CDF) for a Student's t
|
|
distribution with degrees of freedom `v` at a value `x`.
|
|
|
|
If provided `NaN` as any argument, the function returns `NaN`.
|
|
|
|
If provided a non-positive value for `v`, the function returns `NaN`.
|
|
|
|
Parameters

|
x: number
|
|
Input value.
|
|
|
|
v: number
|
|
Degrees of freedom.
|
|
|
|
Returns
