Hello all,

I have to perform ANOVA on the set of three years data. I have the sample size of 100 in all years but in one year few lines didn't grow so I have data only for 95 lines. which method can be used to perform ANOVA and how to represent those missing 5 lines in one year while performing ANOVA?

Thanks

Hi @skal 

Do you mean you would like to impute values to missing data?

Here is an interesting resource to achieve this: https://support.sas.com/content/dam/SAS/support/en/books/multiple-imputation-of-missing-data-using-s...

If you are going to model only the existing data, then PROC GLM is a good starting place.  See this: https://support.sas.com/documentation/onlinedoc/stat/141/glm.pdf .  Now look at the section called Getting Started.  The first example is PROC GLM for Unbalanced ANOVA.  Once you go through that example, you could try it on your data.
