create.Tau2 | R Documentation |
It creates variance component of the heterogeneity of the random effects by decomposing the variance component into matrices of correlation and standard deviations.
create.Tau2(RAM, no.var, Tau1.labels=seq(no.var),
RE.type = c("Diag", "Symm", "Zero", "User"),
level=c("single", "between", "within"),
RE.User=NULL, Transform = c("expLog", "sqSD"),
RE.startvalues=0.05)
