Test coefficients of a model — coef_test • metaforest

Conduct a t-test or z-test for coefficients of a model.

Usage

coef_test(x, par1, par2, distribution = "pt")

Arguments

x: A model.
par1: Numeric or character. Name or position of the first parameter.
par2: Numeric or character. Name or position of the second parameter.
distribution: Character. Which distribution to use. Currently, can be one of c("pt", "pnorm"), for a t-test or z-test, respectively. Defaults to "pt".

Value

Named vector.

Examples

data("dat.bcg", package = "metadat")
dat <- metafor::escalc(measure="RR", ai=tpos, bi=tneg, ci=cpos, di=cneg, data=dat.bcg)
res <- metafor::rma(yi, vi, mods = ~alloc-1, data=dat, method="REML")
coef_test(res, 1, 2)
#> t(11) = 0.87, p = 0.40
