mice.impute.norm.boot {mice} | R Documentation |
Imputes univariate missing data using linear regression with boostrap
mice.impute.norm.boot(y, ry, x, ridge=0.00001, ...)
y |
Incomplete data vector of length |
ry |
Vector of missing data pattern ( |
x |
Matrix ( |
ridge |
Ridge parameter |
... |
Other named arguments. |
Draws a bootstrap sample from x[ry,]
and y[ry]
, calculates regression
weights and imputes with normal residuals. The ridge
parameter adds
a penalty term ridge*diag(xtx)
to the variance-covariance matrix xtx
.
A vector of length nmis
with imputations.
