Illustration of EM algorithm for QTL mapping

Plot of phenotype vs conditional genotype probabilities at each iteration of the EM algorithm. Each point is an individual; pink line segments are at the current estimated averages.

Click on “Next” to go to next iteration and “Back” to go back. Hover over points to see the prior QTL genotype probabilities; hover over line segments to see estimated averages.

The code is on github.
