miMeanSEDefault(estimate, se, df = NA, n = <see below>, sse = F, cov)
estimate
, but containing complete-data standard errors
for the estimates.
df=Inf
(infinity) to obtain degrees of freedom for problems
in which complete-data inferences would use normal or chi-square
rather than t or F distributions.
df
plus
the number of parameters in
estimate
.
TRUE
then
se
is assumed to contain squared standard
errors (variances) rather than standard errors.
estimate
, but containing complete-data covariance
matrices for the estimates, whose diagonal elements are
squared standard errors. If
cov
is supplied then
se
is
ignored.
This function performs core calculations for combining estimates
and standard errors, and is called my
miMeanSE
and its
auxiliary function, including
miMeanSEAux
and its methods, and
miMeanSEList
and
miMeanSEMatrix
.
If
df
or
n
contain non-identical imputations, warnings
are issued and certain averages used. If either of these
are not supplied, or contain missing values (
NA
), then
some components of the output will contain missing values.
