Using the same Credit dataset in the ISLR package with Balance as your dependent variable and Income, Rating, and Age as your independent variable, create a linear-linear, log-linear, linear-log, and log-log model. Based on the R-Squared, which model has the best performance? Note: 1) Balance contains 0's and a 1 needs to be added to the column before you can perform the log transformation (i.e. log(x 1)). 2) For both log-log and linear-log models, simply take the log of each independent variable, like log(X1), log(X2), and log (X3)
