recalcWaldTab.asrtests {asremlPlus} | R Documentation |
wald.asreml
If some or all denDF are not available, either because they are NA or because
F.inc values were not calculated, this function allows the user to specify how
approximate denDF values are to be obtained. This is done through the dDF.na
and
dDF.values
arguments. Note that if denDF values are available in the Wald table then
only those that are NA
will be replaced. The P values are recalculated using F.con,
if present in the wald.tab
, otherwise F.inc is used. It is noted that, as of asreml version 4,
wald.asreml
has a kenadj
argument.
