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.
