Question

Which of the following formulas can be used to calculate the out-of-bag (OOB) error of a random forest model with 5 constituent trees, given the predicted values and actual values? Answer Options Select any one option Clear Answer OOB error = (1/5) * sum of (actual value predicted value) for each tree OOB error = (1/5) * sum of (actual value mean predicted value) for each observation OOB error = (1/5) * sum of (actual value predicted value) for each observation OOB error = (1/5) * sum of (actual value mean predicted value) for each tree

Step 1

The OOB error is calculated using the predictions made by the trees in the forest on the samples that were not used to train those trees. Each tree is trained on approximately 2/3 of the total dataset, and the remaining 1/3 is used to estimate the error. Show more…
