mids.append {NADIA}

Joining mice objects. Used in mice.reuse.

Description

Usage

mids.append(x, y)

Arguments

x

y

Details

Only the data specific aspects are copied (i.e. $data, $imp, $where, $nmis), all other information in 'y' is discarded. Therefore, only the imputation model of 'x' is kept and 'y' must not contain missing data in variables that did not have missing data in 'x' (but the reverse is allowed).

Value

mids object a new mids object that contains all of 'x' and the additional data in 'y'
