Difference between std error in "Parameter Estimates" and "Least Squares Means Table"?

Created: Mar 22, 2021 04:01 AM  |  Last Modified: Jun 10, 2023 1:43 PM (996 views)

I am running mixed effects models and have noticed that the standard error for an effect in the "Parameter Estimates" table is different from the standard error reported in the Least Squares Means table for the same effect. How are they calculated differently? Thanks!

Dear @yovugaro 

please press "?" and click onto the table.

See links to the documentation below.

So the difference is that the one refers to parameter, and the other to each level.

 

Parameter Estimates (jmp.com)

Std Error

The estimates of the standard errors for each of the estimated parameters

 

Effect Details (jmp.com)

Std Error

Shows the standard error of the least squares mean for each level.
