RMSD_DIF theta mean #212

Closed gulbzrhn closed 2 years ago

gulbzrhn commented 2 years ago

In line 152 of the RMSD_DIF() function both mean and standard deviation are assigned to variance estimate from the model, COV_11. This seems like a typo.

if(dentype %in% c('norm', 'snorm')){
mu <- sv$value[sv$name == "MEAN_1"]
sigma2 <- mu <- sv$value[sv$name == "COV_11"]

Indeed it was, good catch.
