Source: R/misc-invgamma.R

Using the same parametrization as Stan. More info here.

dinvgamma_stanlike(x, alpha, beta, log = FALSE)

qinvgamma_stanlike(p, alpha, beta)

Arguments

x

point where to compute the density
alpha

positive real number
beta

positive real number
log

is log-scale used?
p

quantile (must be between 0 and 1)

Value

density/quantile value
