Hi
could someone help me out for the calculation of study weights (manually) in meta analysis. I would like to get the logic or formula for the calculation of those weights. when I use metabin function, I get the information from w.random. I have gone through the metabin function, but the formula appearing inside the function does not give the figures of w.random value.
could someone help me to manually calculation those study weights.
Thanks in Advance
I assume you could use debug() on the function you call, then you can step through, and when there is a variable encountered that contains a value you could see it in the enironment pane, or query it on the console.
Thank you. here is the formula for weight calculation in metabin
w.random <- n.e * n.c/(n.e + n.c) , it covers only total N in experiment and total N in control, which I am able to calculate in Excel and get same output.
subsequently there is no formula but the output metabin has different w.random.
sorry bothering you. I am trying to get a grip on this weight calculate
thanks once again
