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.
I am running a linear regression where the dependent variable is Site Index for a tree species and the explanatory variables are physiographic factors such as elevation, slope, and aspect. None were significant, but after including tree age as independent variable, suddenly elevation and slope become statistically significant.
