Regression Analysis – Linear Model Assumptions Regression analysis offers numerous applications in various disciplines, including finance. Nonlinear regression analysis is commonly used for more complicated data sets in which the dependent and independent variables show a nonlinear relationship. The most common models are simple linear and multiple linear. Regression analysis includes several variations, such as linear, multiple linear, and nonlinear. It can be utilized to assess the strength of the relationship between variables and for modeling the future relationship between them. Regression analysis is a set of statistical methods used for the estimation of relationships between a dependent variable and one or more independent variables. There is no meaningful interpretation for the correlation coefficient as there is for the r 2 value.Updated NovemWhat is Regression Analysis?

Know what various correlation coefficient values mean.

Know how to calculate the correlation coefficient r from the r 2 value.

Understand the cautions necessary in using the r 2 value as a way of assessing the strength of the linear association.

That is, they can be 0 even if there is perfect nonlinear association.

Know that the coefficient of determination ( r 2) and the correlation coefficient ( r) are measures of linear association.Know how to obtain the estimate MSE of the unknown population variance σ 2 using statistical software.Know what the unknown population variance σ 2 quantifies in the regression setting.Summarize the four conditions that underlie the simple linear regression model.Recognize the distinction between a population regression line and the estimated regression line.Know how to obtain the estimates b 0 and b 1 using statistical software.Interpret the intercept b 0 and slope b 1 of an estimated regression equation.Understand the concept of the least squares criterion.Distinguish between a deterministic relationship and a statistical relationship.We will also learn two measures that describe the strength of the linear association that we find in data.

This lesson introduces the concept and basic procedures of simple linear regression. Simple linear regression is a statistical method that allows us to summarize and study relationships between two continuous (quantitative) variables.
