mice.impute.norm.nob: Imputation by linear regression (non Bayesian)
Description
Imputes univariate missing data using linear regression analysis (non
Bayesian version)
Usage
mice.impute.norm.nob(y, ry, x, ...)
Arguments
y
Incomplete data vector of length n
ry
Vector of missing data pattern (FALSE
=missing,
TRUE
=observed)
x
Matrix (n
x p
) of complete covariates.
...
Other named arguments.
Value
A vector of length nmis
with imputations.
Warning
The function does not incorporate the variability of the
regression weights, so it is not 'proper' in the sense of Rubin. For small
samples, variability of the imputed data is therefore underestimated.Details
This creates imputation using the spread around the fitted linear regression
line of y
given x
, as fitted on the observed data.
