Can I use Neural Network to fill in the missing value?

05 May 2016 1 8K Report

I got a data set collected from a hospitals about wound data. Every subject, when admitted, has a check-list filled out by the doctors, describing the depth, the size, the edge and all other criterion of the wound of the subject.

I've got 68 observations, 47 variables but MASSIVE Missing Values!

What should I do? should I try some neural network to fill in the missing values?

Chao Xing

Neural network can do that although it is not necessary for some statistical analysis.

A simple example:

Let the missing variables be output, other variables as input and use complete observations to train the ANN. Then the missing data is found.

The estimated value should be used with caution.
