Student's t-Distribution
The following functions are associated with the Student's t-distribution equation:
Click to copy this expression
dt(x, d)—Returns the probability density for value x.
pt(x, d)—Returns the cumulative probability distribution for value x.
qt(p, d)—Returns the inverse cumulative probability distribution for probability p.
rt(m, d)—Returns a vector of m random numbers having the Student's t-distribution.
Arguments
x is a scalar or vector of real values.
d is a positive integer representing the degrees of freedom. While the distribution equation is meant to be formulated for integers, you can also use real values.
p is a real probability, 0 ≤ p ≤ 1.
m is an integer, m > 0.
