That is right the house is the experimental unit for the fixed effect of the farm. So how is the code will looks like? ... View more

I meant to represent houses that used in the study so I give them numbers from 1 to 6 and the level of the house does not affect the mean of response. Also for farms, I meant to represent each farm. Each house contained about 6000 birds so we visited each house in separate days when birds aged 30 days and we assessed the welfare of birds by using 4 different assessment methods (fixed factors). All of the 4 methods applied in the random order on the same day per house. I need to know how the method of assessment affects the incidence of measured welfare indicators.   Thank you for sharing the paper! ... View more

Thank you for the reply! We measured some welfare indicators for birds in each farm (total 3 farms). Each farm consisted of 2 houses so we had total 6 houses for the experiment. I considered: Farm as random factor House as repeated factor Method as fixed factor (we tested 4 different methods) I need to know the effect of method, house, and interaction between them on the welfare indicators. I wish I clarified what I need? Thanks for offering help! ... View more

Dear All, I am using this Proc Mixed code but I got these errors WARNING: The R matrix depends on observation order within subjects. Omitting observations from the analysis because of missing values can affect this matrix. Consider using a classification effect in the REPEATED statement to determine ordering in the R matrix. NOTE: 3 observations are not included because of missing values. WARNING: Stopped because of infinite likelihood.
