The Crab Molt model looks at measurements of crabs before and after molting. Our main goal was to predict the crab size before molting based on their post-molt measurements. Using a simple model, we got an impressive R-squared value of 0.98, indicating the model predicts well based on the data. And also analyzed the pre-molt and post-molt data. They were similar in distribution, with a small mean difference of about 14.7 units.
