- TDistribution( <Degrees of Freedom>, x )
- Creates cumulative density function (cdf) of t-distribution with given degrees of freedom.
- TDistribution( <Degrees of Freedom>, x, <Boolean Cumulative> )
- If Cumulative is true, creates cumulative distribution function of t-distribution, otherwise creates pdf of t-distribution.
- TDistribution( <Degrees of Freedom>, <Variable Value> )
- Calculates the value of cumulative distribution function of t-distribution at variable value v, i.e. the probability P(X ≤ v) where X is a random variable with t-distribution with given degrees of freedom.
- Example:
TDistribution(10, 0)yields 0.5.
- Note: Returns the probability for a given x-coordinate's value (or area under the t-distribution curve to the left of the given x-coordinate).
