As we mentioned above, the r rows and c columns in the table give us (r - 1)(c - 1) degrees of freedom. But it may not be immediately clear why this is the correct number of degrees of freedom. WebPROC POWER or the POWER2X2 macro computes the power of a test that compares proportions from two independent samples for a range of total sample sizes. The POWERRXC macro computes the power of the Pearson and likelihood ratio chi-square tests (provided in PROC FREQ) for a range of total sample sizes. fish gallery apple valley ca
