Identity theft occurs when someone fraudulently obtains or uses your personal information, such as your name, social security number, or credit card number. The Department of Revenue is committed to preventing refund fraud.
Linear regression is the most basic and commonly used predictive analysis. Regression estimates are used to describe data and to explain the relationship between one dependent variable and one or more independent variables.
Multinomial logistic regression is used when the dependent variable in question is nominal (equivalently categorical, meaning that it falls into any one of a set of categories which cannot be ordered in any meaningful way) and for which there are more than two categories.
