Hi Paige,   This was the result from the LOG   PROC summary data = Cards; class nozzle program sprayer; var yield; output out=_stats_ n=n_yield; run; NOTE: There were 116 observations read from the data set WORK.CARDS. NOTE: The data set WORK._STATS_ has 77 observations and 6 variables. NOTE: PROCEDURE SUMMARY used (Total process time): real time 0.02 seconds cpu time 0.01 seconds  And as far as missing cells - I don't exactly know what could be doing that or even where to look as all my data lines have all pertinent information listed.   Thanks!! ...

I changed NONE to CHK for both the nozzle type and the program, and it still resulted in NON-EST.   I think it may be less to do with the Untreated plots, and more to do with the HF nozzle which was used with sprayer "T" but not sprayer "HB". I say this as the LSMEANS comparisons of nozzle type and sprayer type show only NON EST for the HF nozzle but not for any of the others - including the untreated plots.   Is there anyway to correct the problem if it's not due to the untreated plots?   Thanks! ...

Thanks for the idea! But when I tried that, it still gave me a "NON-EST" for nozzle type and program and sprayer.    One thought I had after this, was that with my sprayer "T" I used 5 nozzle types, and with my sprayer "HB" I used only 4 nozzle types. Could that be the difference in receiving a NON-EST result? And ultimately, if so, how would I correct that?   I could run the data separately by sprayer type, but I wanted to see if the yield result was different for the different sprayer types.    Thanks! ...
