Swapped definition of CR2 and CR3 for vcov in the manual #378

Closed Generalized closed 10 months ago

Generalized commented 10 months ago

I think the definitions of covariance estimator type are swapped:

Allowed vcov includes: "Asymptotic", "Kenward-Roger", "Kenward-Roger-Linear", "Empirical" (CR0), "Empirical-Jackknife" (CR2), and "Empirical-Bias-Reduced" (CR3).

CR2 is the bias-reduced (linearization) by Pustejovsky-Tipton, and CR3 is the leave 1 cluster out (jacknife)

package version: 0.3.5.9002 also in the CRAN version (0.3.6): https://cran.r-project.org/web/packages/mmrm/mmrm.pdf
