Here is a simple intuitive way to understand what those values mean. References: In linear regression, the model specification is that the dependent variable, y is a linear combination of the parameters (but need not be linear in the independent variables). The Simple Linear Regression calculator will also give you three other values, the sum of squares of the regression (SSR), sum of squares of the error (SSE), and sum of squares of the total (SST). As the linear regression has a closed form solution, the regression coefficients can be efficiently computed using the Regress method of this class.
In linear regression, the model specification is that the dependent variable, y is a linear combination of the parameters (but need not be linear in the independent variables). Simple linear regression is used to estimate the relationship between two quantitative variables. Linear regression analysis is the most widely used of all statistical techniques. The slope of the line is b, and a is the intercept (the value of y when x = 0). Recognize the distinction between a population regression line and the estimated regression line.

Know how to obtain the estimates b 0 and b 1 from Minitab's fitted line plot and regression analysis output. Interpret the intercept b 0 and slope b 1 of an estimated regression equation. Simple linear regression is useful for finding relationship between two continuous variables.Ī linear regression line has an equation of the form Y = a + bX, where X is the independent variable and Y is the dependent variable. Understand the concept of the least squares criterion. Linear regression is used for finding linear relationship between target and one or more predictors. In statistics, linear regression is a linear approach to modeling the relationship between a scalar response (or dependent variable) and one or more explanatory variables (or independent variables).
