I want to analyses the proportion of swimming sperm of three species of fish in two salinities. To analyse the proportion of swimming sperm in a Generalized Linear Model, I would use a Binary Logistic model with swimming sperm as dependent and the total number of sperm and the number of events occurring in each set of trials. However, we have tested sperm from each male in two different salinities i.e. a repeated design. Hence, I want to use a Generalized Linear Mixed Model with repeated measures. However, I fail to find how I do a Binary Logistic model with swimming sperm as dependent and the total number of sperm and the number of events occurring in each set of trials. Is it doable in SPSS? If so, how do I proceed? (Using the arcsine of the proportion of swimming sperm is not an option)
