'missForest' is used to impute missing values particularly in the case of mixed-type data. It can be used to impute continuous and/or categorical data including complex interactions and nonlinear relations. It yields an out-of-bag (OOB) imputation error estimate.

missForest is a nonparametric, mixed-type imputation method for basically any type of data. Here, we host the R-package "missForest" for the statistical software R.

April 4, 2025 - Package: missForest Authors: Daniel J. Stekhoven Category: Single Imputation Use-Cases: Single Imputation of continuous and/or categorical data. Popularity: Description: The function ‘missForest’ in this package is used to impute missing values particularly in the case of mixed-type data.

The missForest package in R uses non-parametric techniques to train random forests on observed (not missing) data and uses that information to predict missing values.

missForest is a nonparametric imputation method for mixed-type tabular data in R. It handles numeric and categorical variables simultaneously by iteratively training random forests to predict missing entries from the observed ones.

The missForest package provides nonparametric missing-value imputation for mixed-type data (continuous and categorical). It models each variable with missingness using random forests that learn complex interactions and nonlinear relations and returns out-of-bag (OOB) error estimates.

January 1, 2012 - We propose and evaluate an iterative imputation method (missForest) based on a random forest. By averaging over many unpruned classification or regression trees, random forest intrinsically constitutes a multiple imputation scheme.

August 16, 2020 - The reason I want to use this approach: imagine your training dataset is 1M observations, and you are building a model that must be ran hourly on 1k observations. The 'quality' of the missing value imputations will surely be higher if you use those 1M observations to 'inform' the missForest() algorithm, as apposed to simply running the algorithm on the 1k observations alone.
