Repeated Measures analysis doesn't return results for one treatment

jrhughes — Thu, 08 Jun 2023 21:03:12 GMT

Hi Folks,

I'm at a loss. My experiment is cells with 4 different treatments and over the course of 5 time points. I have 5 biological replicates of this experiment. The script doesn't return data for one of my treatments. They are called: Control, Catalase, LewisA, LewisX.

I'm not even sure what information I should share.

Please help.

Thanks in advance.

Fit Model(
	Y( :SqrtLive ),
	Effects( :Treatment[:Time], :Time ),
	Personality( "Mixed Model" ),
	Run( Random Effects Covariance Parameter Estimates( 0 ) )
)

Hi,
Could you provide the data table or a mock example of the table if your data is confidential.
Also, at first glance, you Nested Treatment within Time which is rather unusual: did you mean to Cross (i.e. :Treatment * :Time) to test the interaction?
Best,
TS

I think that you might actually be referring to the practice of reporting the parameter estimates for all but the level of the categorical factor.

Click the red-triangle at the top of the platform and select Estimates > Expanded Estimates to see the estimates for all the levels.
