Dear statalist, How to make a contingency table of my following panel data and report the chi-square value? fund code female institute individual time ----------------+------------------------------------------------------- 000001.OF 0 0.234 0.766 200506 000002.OF 1 0.201 0.799 200506 ⋯⋯ 000001.OF 0 0.283 0.717 201012 000002.OF 1 0.256 0.744 201012 I wish to make a contingency table like the following and test whether females attracts more individual investors than institute investors, as well as whether females attract more institute/individual investors than males. Male Female ----------------+---------------------------- institute f1 f2 individual f3 f4 (Basically, f1+f2+f3+f4=1. I just wish to test whether f1=f2, f1=f3, f3=f4, f2=f4 at the same time using chi-square) I tried the following codes but failed: . tabulate institute individual too many values r(134); . tab institute individual, ch too many values r(134); . symmetry institute female too many values r(134); . symmetry institute female, exact too many values r(134); . symmetry institute female, contrib too many values r(134); Could anyone kindly enlighten me how to do this?
