Ajustes Yield for multiple years

Heldermedice — Fri, 29 Sep 2017 21:30:56 GMT

Hi,

Could anyone suggest a code for calculating a multiyear analysis for adjusted yields?

What does your starting data look like? (sample data please).

What are you adjusting for? Stock splits? Other events?

Yield of what? Nuclear weapons? Grain fields? Yards in NFL Games?

Thanks for the answer mkeintz,

I am an agronomist, so I have to calculate genetic gain of corn yield during 4 years.

I must compare the means but I can´t use the Proc Means or Proc Glm.

I am trying to use Proc Mixed to calculate the Adjusted Means by using a mixed models.

Follow my sample of data:

Hi ballard,

Yield of grain corn.

Does this sas note Usage Note 24497: Can I get adjusted or least-squares means (LSMEANS) in PROC SURVEYREG? address your question?

Also the sas documentation has a section (for GLM) on the LSMEANS Statement. And the documentation for the MEANS statement includes this guidance: "Note that the arithmetic means are not adjusted for other effects in the model; for adjusted means, see the section LSMEANS Statement."
