Reference no: EM133018938

Now use backward stepwise regression to build a model. Your model should start with all of the possible predictors. You may find it useful to add the line of code "options(scipen = 999)" as a line of code before running your model. This will prevent the results from being displayed in somewhat unhelpful scientific notation. Be sure to look at your "allmod" output before proceeding. Note that the allmod output will be pretty long because of the large number of levels in the various categorical variables.
