lndIChisq
computes the log of an Inverted Chi-Squared Density.
lndIChisq(nu, ssq, x)
nu |
d.f. parameter |
ssq |
scale parameter |
x |
ordinate for density evaluation |
Z= nu*ssq/chi^2_{nu}, Z ~ Inverted Chi-Squared.
lndIChisq
computes the complete log-density, including normalizing constants.
log density value
This routine is a utility routine that does not check the input arguments for proper dimensions and type.
