The LINEST function uses the least squares regression method to calculate a straight line that best explains the relationship between your variables and returns an array describing that line. The dependent variables used in regression analysis are also called response or predicted variables, and independent variables are also called explanatory variables or predictors. A linear regression line has an equation of the kind: Y= a + bX; With many things we try to do in Excel, there are usually multiple paths to the same outcome. Some paths are better than others depending on the situation.
