rhyp function from fBasics

Dear R People: There is a function from the fBasics library to get the probability and quantiles for the hyperbolic probability function. Is there one that will estimate parms of the hyperbolic probability function from a data set, please? Thanks in advance!

Erin, You can use MASS::fitdistr to do this, I believe. library(fBasics) library(MASS) x <- rhyp(1000, alpha = 2, beta = 1, delta = 1) fitdistr(x, dhyp, list(alpha = 1, beta = 0.5, delta = 0.5)) --sundar
