[R] Sample size Determination to Compare Three Independent Proportions

[AbouEl-Makarim Aboueissa]

Dear All: good morning



*Re:* Sample Size Determination to Compare Three Independent Proportions



*Situation:*



Three Binary variables (Yes, No)

Three independent populations with fixed sizes (*say:* N1 = 1500, N2 = 900,
N3 = 1350).

Power = 0.80

How to choose the sample sizes to compare the three proportions of “Yes”
among the three variables.



If you know a reference to this topic, it will be very helpful too.



with many thanks in advance
