    Freidman test with missing values?




    I have a set of data at four time points, but some subjects only two out of the four time points. Can I still use Friedman test for this in SPSS?

    Some additional information would be useful. What is your study about, what do you want to find out?
    What was measured? How many subjects were there in total? How many subjects have missing data?
    By "two out of the four time points" do you mean, only the first 2 out of 4, or maybe for example
    1 & 3, or 2& 4 etc.?

    With kind regards
