Computes the estimate, standard error, and an adjusted Wald confidence interval for a linear contrast of proportions from two or more studies.
meta.lc.prop1(alpha, f, n, v)
alpha level for 1-alpha confidence
vector of frequency counts
vector of sample sizes
vector of contrast coefficients
Returns 1-row matrix with the following columns:
Estimate -estimated linear contrast
SE - standard error
LL - lower limit of the adjusted Wald confidence interval
UL - upper limit of the adjusted Wald confidence interval
