Multivariate Imputation By Chained Equations (MICE) algorithm for missing values | Machine Learning

In this tutorial, we'll look at Multivariate Imputation By Chained Equations (MICE) algorithm, a technique by which we can effortlessly impute missing values in a dataset by looking at data from other columns and trying to estimate the best prediction for each missing value.

We'll look at the different types of missing data, viz. Missing Completely at Random (MCAR), Missing at Random (MAR) and Missing Not at Random (MNAR).

Machine Learning models can't inherently work with missing data, and hence it becomes imperative to learn how to properly decide between different kinds of imputation techniques to achieve the best possible model for our use case.

Best video on MICE so far, the name made it sound very complex but you broke it down beautifully for me. Thank you.

[ashishchawla]

One of the best video I have seen which explains MICE in such a simple and efficient way, Great work 👌.
It would be really great if you could make a video to explain MICE for categorical also, considering a scenario when both numerical and categorical missing data are involved

Thank you so much for sharing this concise and straight-to-the-point tutorial. I am about to collect data for my dissertation, and I was researching how to address missing values. This video was helpful.
