isplit: Split a 'mids' Object into List of 'mids'

In jesse-smith/futuremice: A Future for MICE

Split a mids Object into List of mids

Description

isplit() is the inverse of ibindlist() and converts a single mids object into a list of mids objects containing the largest number of chains possible while

1. distributing chains evenly among mids objects and

2. keeping the number of chains per object <= chunk_size. The resulting number of objects is specified implicitly through mids$m and chunk_size.

Usage

isplit(mids, chunk_size = 1L)

Arguments

mids	A mids object, as created by mice::mice()
chunk_size	The number of to allocate to each smaller mids object in the resulting list. If mids$m %% chunk_size != 0, a smaller chunk_size will be used.

Value

A list of mids objects

Examples

# Create `mids` object
mids <- mice::mice(mice::nhanes, m = 2L, maxit = 1L)

# Split into two - 1 imputation per object
mids_list <- isplit(mids)
mids_list
