mipo
: Multiple imputation pooled objectThe mipo
object contains the results of the pooling step.
The function pool
generates an object of class mipo
.
mipo(mira.obj, ...)# S3 method for mipo
summary(
object,
type = c("tests", "all"),
conf.int = FALSE,
conf.level = 0.95,
exponentiate = FALSE,
...
)
# S3 method for mipo
print(x, ...)
# S3 method for mipo.summary
print(x, ...)
process_mipo(z, x, conf.int = FALSE, conf.level = 0.95, exponentiate = FALSE)
An object of class mira
Arguments passed down
An object of class mipo
Logical indicating whether to include
a confidence interval. The default is FALSE
.
Confidence level of the interval, used only if
conf.int = TRUE
. Number between 0 and 1.
Flag indicating whether to exponentiate the coefficient estimates and confidence intervals (typical for logistic regression).
An object of class mipo
Data frame with a tidied version of a coefficient matrix
The summary
method returns a data frame with summary statistics of the pooled analysis.
An object class mipo
is a list
with
elements: call
, m
, pooled
and glanced
.
The pooled
elements is a data frame with columns:
estimate |
Pooled complete data estimate |
ubar |
Within-imputation variance of estimate |
b |
Between-imputation variance of estimate |
t |
Total variance, of estimate |
dfcom |
Degrees of freedom in complete data |
df |
Degrees of freedom of $t$-statistic |
riv |
Relative increase in variance |
lambda |
Proportion attributable to the missingness |
fmi |
Fraction of missing information |
The names of the terms are stored as row.names(pooled)
.
The glanced
elements is a data.frame
with m
rows.
The precise composition depends on the class of the complete-data analysis.
At least field nobs
is expected to be present.
The process_mipo
is a helper function to process a
tidied mipo object, and is normally not called directly.
It adds a confidence interval, and optionally exponentiates, the result.
