The metatest package fits meta regression models and computes various statistics to test the significance of the coefficients.
Changes in version 1.0-4
o Replaced calls to as.real (soon to be deprecated) by as.double.
Changes in version 1.0-3
o Fixed a bug in the degrees of freedom for the t-test (was n-1, now is
n-ncol(x), where x is the design matrix). Note that the Huizenga et al
paper also contains this error.
Changes in version 1.0-2
o Updated the reference to our paper which has appeared in the British
Journal of Mathematical and Statistical Psychology.
Changes in version 1.0-1
o Fixed a bug in the p-value of the test of the significance of the
likelihood ratio test of the between studies variance which is by
default divided by 2 (as per Berkhof & Snijders, 2001), which led to
odd results (ie p-value of 0.5) when the ratio is zero. This has now
been set to the value of 1.
