mipo
)The mipo
object is generated by the pool
function from a
link[=mira-class]{mira}
object. The mipo
class of objects has methods for
the following generic functions: print
, summary
.
.Data
:Object of class "list"
containing the
following slots:
call
:The call that created the mipo
object.
call1
:The call that created the mira
object that was used
in call
.
call2
:The call that created the mids
object that was used
in call1
.
data
:A copy of the incomplete data set.
nmis
:An array containing the number of missing observations per column.
m
:Number of multiple imputations.
qhat
:An m
by npar
matrix containing the complete
data estimates for the npar
parameters of the m
complete data
analyses.
u
:An m
by npar
by npar
array containing the
variance-covariance matrices of the estimates of the m
complete data analyses.
qbar
:The average of complete data estimates. The multiple imputation estimate.
ubar
:The average of the variance-covariance matrix of the complete data estimates.
b
:The between imputation variance-covariance matrix for the estimates.
t
:The total variance-covariance matrix for the estimates.
r
:Relative increases in variance due to missing data.
dfcom
:Degrees of freedom in the hypothetically complete data: the sample size minus the number of free parameters.
df
:Degrees of freedom associated with the t-statistics.
fmi
:Fraction of missing information.
lambda
:Proportion of the variation attributable to the missing
data: (b+b/m)/t.
