Thanks for your reply.
But the mean y of sex(f) and sex(m) can't be negative since the min and max of
y is 1632.5 and 6410.6 respectively.
And your code's result:
sex(f): -1255.56
sex(m):-1118.73
The above result isn't correct since they are negative.
Thanks

But I don't want the original mean y ,but the "corrected mean y" of analysis of
covariant.
Also,the difference of original mean y is not 136.83,which is the difference of
the "corrected meany".

Hi all:
My data is in the attachment.
I want to analysis the mean difference of y between 2 sex.
My code:
result_lm<-lm(y~factor(sex) + x1 + x2)
summary(result_lm)
The result of "factor(sex)m" 136.83, is the mean difference of y between 2
sex,and the corresponding p value is 0.07618.
