Power of test comparing independent proportions.
In clinical studies, trial size may be bounded by scarcity of resources and cannot be planned at will to attain some given power level as provided by sample size tables. In such a situation it may be useful to compute power consequent to the limited trial size. A procedure in BASIC is provided for approximate computation of power of a test comparing independent proportions when trial size is known to be limited.
