%description
A tool for multiply imputing missing data using 'MIDAS', a deep learning
method based on denoising autoencoder neural networks (see Lall and
Robinson, 2022; <doi:10.1017/pan.2020.49>). This algorithm offers
significant accuracy and efficiency advantages over other multiple
imputation strategies, particularly when applied to large datasets with
complex features. Alongside interfacing with 'Python' to run the core
algorithm, this package contains functions for processing data before and
after model training, running imputation model diagnostics, generating
multiple completed datasets, and estimating regression models on these
datasets. For more information see Lall and Robinson (2023)
<doi:10.18637/jss.v107.i09>.
