You can use an ESTIMATE statement in PROC MIXED to compare two genotypes: estimate 'gen1-gen2' | gen 1 -1; The predicted difference and the standard error will be produced. ... View more

Hi Everyone, I am having similar problem on the issue of convergence using proc mixed. Three of my traits are in t/ha and the other one is in percentage. Two of the traits converged. I am thinking of rescaling by dividing by 10 to see if that would solve the problem. Is it a good idea? ... View more

One route might be adjusting the default tolerance up so that you get convergence (convf, convg or convh options)? https://support.sas.com/documentation/cdl/en/statug/63347/HTML/default/viewer.htm#statug_mixed_sect008.htm#statug.mixed.procstmt_convf   -unison  ... View more

Hi everyone, I have got temporary solution to the posted question about memory issue. What I did is to change ddfm =kr in the model statement to ddfm=satterth. I also put all my ods output statement outside proc mixed and not within proc mixed procedure. I used as well ods noresults. ... View more

OK, in that case please post the SAS log of the program you are using to test a connection to Oracle, including any notes and errors. ... View more

Thanks for the quick response. I run both SAS 9.4 and Oracle database 11g xe edition on a single window 10 64-bit enterprise edition. Do I need to install oracle client for me to connect to Oracle database 11g xe  from SAS? My oracle runs perfectly both in sqlplus and oracle sql developer likewise the SAS. The big challenge is to connect database from SAS   Please let me know if oracle database 11g xe edition requires oracle client for me to connect it from SAS.   Thanks ... View more

The INFLUENCE option produces internally and externally studentized marginal (not conditional) residuals.   ... View more

Based on my reading of the MIXED documentation, it does not look like you can obtain externally studentized conditional residuals. The INFLUENCE option produces internally and externally studentized marginal residuals.    The MIXED Procedure | Details | Residuals and Influence Diagnostics      the output dataset "resid" includes the internally conditional studentized residual which is dissimilar from internally conditional studentized residual returned by output dataset "studres" from Influence. I expected to see the same result. Why difference in the result?     Because they are different kinds of residuals. The output dataset "studres" from INFLUENCE contains internally studentized marginal (not conditional) residuals; those will match the internally studentized marginal residuals in the output dataset from OUTPM= , but are of course different than internally studentized conditional residuals from OUTP= .   From a practical point of view, if I couldn't obtain externally studentized conditional residuals, I would use internally studentized conditional residuals.    ...

Thanks for this response. My worry with the likelihood ratio tests for mean structures in proc mixed is that  the difference of the -2 loglikelihood will have chi distribution with zero degree of freedom. From the example you gave, there is one covariance parameter in each of the fitted model which implies different of zero degree of freedom. This is the problem I am having with the analysis I am doing. Please clarification. ... View more
