The “training” dataset is a 50% random sample of all counties with at least 10,000 residents available from the Opportunity Atlas. You will use predictors from Google DataCommons to predict the variable kfr_pooled_p25 in the . other . half of these data. There are about 5,000 possible covariates available from Google DataCommons!

If the number of cases in the training set is N, then sample of N cases is taken at random but with replacement. This sample will be the training set for growing the tree. If there are M input variables, a number m

It should be noted that Mallow’s Cp is itself a random variable dependent on the data. Based on our limited sample size, it is unclear which model is the most accurate but it is reasonable to conclude that both disease duration and PVF are significant players in predicting EDSS since they are used in all of the contending best models.

The RF, in particular, introduces additional variance by using a random sample of features for each individual sub-model. However, ensemble algorithms come at the cost of longer processing time. To maximise the generalisability of our findings, we processed two target values with substantially different characteristics.
