Imputation by a Weighted Linear Normal Regression
Description
Imputation by a weighted linear normal regression.
Usage
mice.impute.weighted.norm(y, ry, x, ridge = 1e-05, pls.facs = NULL,
imputationWeights = NULL, interactions = NULL, quadratics = NULL, ...)
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.
|
ridge |
Ridge parameter in the diagonal of old{X}'old{X}
|
imputationWeights |
Optional vector of sampling weights
|
pls.facs |
Number of factors in PLS regression (if used). The default is NULL
which means that no PLS regression is used for dimension reduction.
|
interactions |
Optional vector of variables for which interactions should be created
|
quadratics |
Optional vector of variables which should also be included as quadratic effects.
|
... |
Further arguments to be passed
|
Value
A vector of length nmis=sum(!ry) with imputed values.
