I am guessing that you want a random variate generator that generates log-logistic random variates. GSL provides a random variate generator that generates logistic random variates. One method that should work well is to generate a logistic random variate X and then the log-logistic random variate is exp( X ). This is the method that GSL uses to generate lognormal variates starting from normal (Gaussian) variates. You will need to know how to translate from log-logistic parameters to logistic parameters. If this is not enough you might look at the books of Devroye or Kleijnen and van Groenendaal or Law and Kelton. -- JDL _______________________________________________ Help-gsl mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-gsl
