      Least squares linear regression is a method for predicting the value of a dependent variable Y, based on the value of an independent variable X. Prerequisites for Regression. Simple linear regression is appropriate when the following conditions are satisfied. The dependent variable Y has a linear relationship to the independent variable X.

      In other words, a positive (negative) value indicates that the biological age of the sample is higher (lower) than expected based on chronological age. Specifically, these measures were defined as residuals (observed minus predicted) resulting from a simple linear regression model that regressed biological age on chronological age.

      The Simple Linear Regression Model. Least squares estimation deals with the systematic component which addresses the relationship between the predictor and the outcome. But we haven’t discussed the random component present in any statistical model. Here is the simple linear regression model. Y is the unknown dependent variable

      80% of the variability in BAC can be explained by the variability in Number Beers Consumed through the linear regression line. Subject to interpretation, but Seems to do pretty well, 80% is a fairly high value. 8. Conduct the Simple Linear regression, and write the equation of the regression line.

      The goal of simple linear regression is to minimize this quantity, and the estimated regression equation is the model that indeed has the smallest SSE. The activity asks students to calculate SSE using their calculator and to do this they simply need to square the residuals and then find the sum.

      = Simple Linear Regression (SLR) = estimate the intercept and slope in linear relationships. Example. From a recent issue of Road and Track magazine, investigation of the relationship between Time (in seconds) to reach 60 mph and Horsepower of cars. The estimated relationship: Time to 60mph = 9.8962 – 0.0122*HP. The correlation is -0.8374.
