We have a dataset containing 180 email messages. 90 of the email messages were identified as spam and 90 were identified as not spam. Fout features were selected for the task of building a classification model to identify if an email was spam (positive class) or not (negative class). A tabhe explaining the features and some R output is shown below. spaindat = spandat $>.8 mutate(preds = predict( (glm1, type = "response") \%sx round()) im = caret: ; confusionMatrix(data i= factor(spandatSpreds). reference = factor (spandatsis_spam), positive = "1.1) spandat = spandot 10x mutate(preds = predict(glm1, type = "response") os round()) cm = caret:: confusionMatrix(data = factor(spandatspreds), reference = factor ( spomdatsis, 5pam), cmstable positive = "1") Using the confusion matrix output and noting that the positive class is the presence of spam (coded as 1). calculate the following performance me For each, report your answer to 2 decimal places. Based on the output above, which predictor would you drop first in a backwards elimination feature selection. (intercept) prop_dollar. prop_profit avg_capital_run money
