meta.lc.prop2 | R Documentation |
Computes the estimate, standard error, and adjusted Wald confidence interval for a linear contrast of 2-group proportion differences from two or more studies.
meta.lc.prop2(alpha, f1, f2, n1, n2, v)
alpha |
alpha level for 1-alpha confidence |
f1 |
vector of group 1 frequency counts |
f2 |
vector of group 2 frequency counts |
n1 |
vector of group 1 sample sizes |
n2 |
vector of group 2 sample sizes |
v |
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
