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.

Using the linear regression function on your calculator, find the line of best fit (ln N = m(ln t) + b) and the correlation coefficient (r-value). Line of Best Fit: Correlation Coefficient: IV. Order the three scatter plots (t vs. N, t vs. ln N, ln t vs. ln N) from most linear to least linear.

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.

If these points were eliminated, the r value would get closer to -1 and the r2 value would be closer to 1 … so the new model would be a better predictor. Use your regression equation to predict the number of drive-in movie screens in the years 2001, 2005 and 2007.

Use Stat > Regression > Regression to find the regression equation AND predict BAC when “beer” is 5. To predict the values, use Options and then type in the x value of your variable there. Use Stat > Regression > Regression to find the regression equation AND make a residual plot of the residuals versus the explanatory variable.
