Impute the covariance matrix of incomplete data so that factor
analysis can be performed. Imputations are made using multiple imputation
by Multivariate Imputation with Chained Equations (MICE) and combined with
Rubin's rules. Parametric Fieller confidence intervals and nonparametric
bootstrap confidence intervals can be obtained for the variance explained by
different numbers of principal components. The method is described in
Nassiri et al. (2018) <doi:10.3758/s13428-017-1013-4>.

Useful R code for the Estimation of Migration
The migest package contains a collection of R functions
that are useful to estimate migration when there is missing
data. Included is the ffs routine to estimate migration flows
from stock data, as well as various other functions to
indirectly estimate flows where marginal totals are known.
Functions are illustrated with dummy data.

Methods for the Indirect Estimation of Bilateral Migration
Indirect methods for estimating bilateral migration flows in the presence of partial or missing data. Methods might be relevant to other categorical data situations on non-migration data, where for example, marginal totals are known and only auxiliary bilateral data is available.
