Location-scale Student-t

stats::dt() only knows the standardized t, and Stan's student_t is the location-scale one. These three wrap the shift and the scale, including the -log(scale) Jacobian on the density, and take their arguments under the names the registry uses.

Usage

dstudent_t(x, df, location = 0, scale = 1, log = FALSE)

pstudent_t(q, df, location = 0, scale = 1)

qstudent_t(p, df, location = 0, scale = 1)

Arguments

x, q, p

Value, quantile or probability.

df, location, scale

Distribution parameters.

log

Return the log density.
