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
