topic Restricting the value of posterior means in proc mcmc in Statistical Procedures https://communities.sas.com/t5/Statistical-Procedures/Restricting-the-value-of-posterior-means-in-proc-mcmc/m-p/249999#M13160 <P>Hi Team,</P><P>&nbsp;</P><P>Please suggest how to restrict the posterior mean value in Proc MCMC output? i.e. if I need the posterior mean for a particular parameter to lie within a particular range, then how shall I do it in SAS? I have attached one Proc MCMC output for the reference.</P><P>In that I need to change the posterior mean of "<SPAN>SOV_Mohani_b5</SPAN>" as a <STRONG>positive value.</STRONG> Although the variable has negative correlation value with the dependent variable in the raw data. Here I am generating posterior samples to remove auto-correlation from the same Linear Mixed Model. Please suggest a solution at the earliest.</P><P>&nbsp;</P><P>Thanks!</P><P>&nbsp;</P><P>Regards,</P><P>Piyush</P> Sun, 14 Feb 2016 20:06:45 GMT piyushstats 2016-02-14T20:06:45Z Restricting the value of posterior means in proc mcmc https://communities.sas.com/t5/Statistical-Procedures/Restricting-the-value-of-posterior-means-in-proc-mcmc/m-p/249999#M13160 <P>Hi Team,</P><P>&nbsp;</P><P>Please suggest how to restrict the posterior mean value in Proc MCMC output? i.e. if I need the posterior mean for a particular parameter to lie within a particular range, then how shall I do it in SAS?
