Dear R users, I want to generating random samples from Inverse Gaussian distribution . How can I do? and what package should I install? Thanks. Shirin [[alternative HTML version deleted]]

...my problem: I was using optim to estimate parameters of a model and I get this error message "Error in optim(x0, fn = riskll, method = "L-BFGS-B", lower = lbs, upper = ubs, : L-BFGS-B needs finite values of 'fn'" Below is the R code I have written. library('GeneralizedHyperbolic') data=read.table(file="MSCI_USA.csv",sep=',',header=T) data=data[1:8173,] #starting value x0 <- c(-0.011,0.146, 0.013, 0.639, 0.059,0.939, -0.144 , 1.187, 1.601, -0.001) #lower bound and upper bound lbs <- c(-5, -5, -5, -0.99999, 0.00001, 0, -1...

...t the data from a graph by providing calibration points * DistributionUtils (0.1-0) David Scott http://crantastic.org/packages/DistributionUtils This package contains utilities which are of use in the packages I have developed for dealing with distributions. Currently these packages are GeneralizedHyperbolic, VarianceGamma, and SkewHyperbolic. Additional packages are under development. Each of these packages requires DistributionUtils. Functionality includes sample skewness and kurtosis, log-histogram, moments by integration, changing the pint about which a moment is calculated, functions for...

http://r.789695.n4.nabble.com/file/n3216865/Inverse_Gamma.png Hello, I am seeking help in estimating the parameters of an inverse gamma distribution (from the 'actuar' package) using a function like 'fitdistr'. Unfortunately I haven't found such a package using findFn('fit Inverse Gamma') from the 'sos' package and was therefore hoping someone might be aware
