StudentT {brms} R Documentation

## The Student-t Distribution

### Description

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

### Usage

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)

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


### Arguments

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

### Details

See vignette("brms_families") for details on the parameterization.
