The Student-t Distribution

Density, distribution function, quantile function and random generation for the Student-t distribution with location mu, scale sigma, and degrees of freedom df.

dstudent_t(x, df, mu = 0, sigma = 1, log = FALSE)

pstudent_t(q, df, mu = 0, sigma = 1, lower.tail = TRUE, log.p = FALSE)

qstudent_t(p, df, mu = 0, sigma = 1, lower.tail = TRUE, log.p = FALSE)

rstudent_t(n, df, mu = 0, sigma = 1)

Arguments

x: Vector of quantiles.
df: Vector of degrees of freedom.
mu: Vector of location values.
sigma: Vector of scale values.
log: Logical; If TRUE, values are returned on the log scale.
q: Vector of quantiles.
lower.tail: Logical; If TRUE (default), return P(X <= x). Else, return P(X > x) .
log.p: Logical; If TRUE, values are returned on the log scale.
p: Vector of probabilities.
n: Number of draws to sample from the distribution.
