Dear Madan It is good to see codes in R. Hope you will write code in R for those distribution for which only kernel of density is known (normalization constant does not exist). This will help users of Bayesian. Attaching simulation.doc for those who are unable to open .docx file. If possible please attach .pdf file. Conversion in .doc file is distorting mathematical expression I  have created a  folder for simulation under “Link” and “File” tab of our group. Please put all maters in those places. It will help users in future.

Please see the trailing mail for the details of the query. I recieved a number of responses. I have summarized the responses in the form of the concised solution of the query in the attached document. I hope it will be helpful to members who have same query.

I don't want to use the routines like rnorm, rcaucy etc. My intention is to provide the density function and not the distribution name.   For example, I want to generate data from the distribution with density function f(x)=4*x^3, where 0<=x<=1. How can generate 100 data points from this density function?   Thanks in advance.   Regards ------------ -- Madan Gopal Kundu PhD Scholar Indiana University Purdue University Indianapolis (IUPUI) Indianapolis, Indiana 46202, USA Web: http://mgkundu. webs.com/ Cell: 317-657-1180 Sir Ronald Aylmer Fisher: "To call in the statistician after the experiment is done may be no more than asking him to perform a post-mortem examination: he may be able to say what the experiment died of."
