TDIST
Calculates values for a Student's t-distribution.
Syntax:
TDIST(x; r; mode)
- x is the value at which the distribution is calculated.
- r, an integer >=1, is the degrees of freedom parameter for the t-distribution.
- mode may be 1 or 2, to calculate the one or two tailed probability.
- TDIST returns the probability density function for the t-distribution, calculating:
Example:
TDIST(0.5; 2; 2)
- returns approximately 0.666.
