Script to estimate power

[cbautista]

Hi all,

I have the following structure data

a b c d
2 1 124 295
8 5 260 149
239 116 29 38
6 13 262 141
......

and I would like to calculate the corresponding power for two proportions
for an alpha=0.05.

I have over 30,000 records, so maybe somebody has a script to do so. it
would take several weeks/months to calculate the power for each record by
hand.

Thanks in advance,

/Christian

What do your four columns reprsent?
What would you do for each record if you had to do it by hand?
