Before you treat your discrete variables as categorical, consider whether you should at least evaluate the linear component by treating it as continuous. For variables with partial orderings, or with both linear and nonlinear components, consider combining continuous and categorical variables together.
Believe it or not, your credit score will be higher if you have 6-10 credit accounts than if you have just one or two. Here are action items to consider to improve this section of your credit report: 1  Pay on time. 2  Credit cards. 3  Utility bills. 4  Library dues.
Work on your credit score. Paying down credit cards to 30% or less of your total available credit can increase your score dramatically in as little as 30 days. Pay off any and all consumer debts as much as possible as these liabilities, even though they may be small, erode your income.
