 Calculation using proportions [Power / Sample Size]

Post reply
Dear All,

I need a clarification regarding the sample size calculation by using proportions, differences and delta for clinical trails. And please suggest me the formula used for this calculation. And in how many types we can calculate the sample size in any type of studies? thanks in advance.

Regards,
MGR

Dear MGR,

it's simply not possible to answer your question in a post.

There's a textbook covering this topic:
S-C Chow, J Shao and H Wang
Sample Size Calculations In Clinical Research
Marcel Dekker, New York (2003)
