lsmeans

[Zahra_Pakbaz]

hello 

I use lsmeans to adjust my data. the outcome shows the result with decimal df. I want to know is it normal that df will be decimal? and how can I infer df for lsmeans? and also is it normal that df is different from each other? 

this is some part of my result 

N	Condition.x	Genotype.x	lsmean	SE	df	lower.CL	upper.CL
1	C	B1	2.580171	0.150533	5.144451	2.196458	2.963884
2	T	B1	1.39861	0.15061	5.16151	1.01507	1.782149
3	C	DZ	2.660867	0.150933	5.190571	2.277128	3.044606
4	T	DZ	1.489736	0.150499	5.126756	1.105725	1.873747
5	C	LR41	2.52188	0.208292	18.82806	2.085651	2.958109

What SAS code did you submit?

[Zahra_Pakbaz]

leastsquare_root_lengh_R_1_2_3_4 <- lsmeans(rootlength_REP1_2_3_4,
pairwise ~ Condition.x* Genotype.x ,
adjust = "tukey",pbkrtest.limit = 6950,lmerTest.limit = 6950) ### Tukey-adjusted comparisons

R1234_LSMEANS_DATA <-
summary(leastsquare_root_lengh_R_1_2_3_4)
write.csv(R1234_LSMEANS_DATA,
"./LSmeans_R1234_Length.CSV")

this is the  script that i use. I whant to know how df calculate for lsmeans and what is its meaning? thank you very much

This is not SAS code.

[Zahra_Pakbaz]

 yes but just I what to know how df  will be calculate ? and what mean dose it have?

[PaigeMiller]

I don't know what the language is that you used, and I don't know how that language does a calculation of non-integer degrees of freedom. You should really ask in a forum for that specific language, and the people there probably can explain what that language is doing.

this is R script. ok thank you
