Dear Michael, Thanks very much for your quick response. My outcome is not binary. Outcome has more than 2 values (levels) and I have counts for the levels. I have not written a code yet. I would like to know if escalc() can handle categorical outcome data (more than 2 proportions). If so, how can I input the counts of each level of the categorical outcome to this function. Hope it is little clear now. Dushanthi You do not give us very much to go on here. When you say your outcome >is proportions do you mean your outcome has more than two values and > you are generating (or have been provided with) several proportions > for each study or do you mean it is a binary variable?
