• 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.
