| APPLET | SOURCE | DESCRIPTION |
|
| Correlation and Regression Demo | W.H. Freeman & Co. | Users add data to a scatterplot and then try to draw the regression line, guided by a bar display that shows how much more error the user line has compared to the least squares line. more |
|
| Linear Regression Applet | Exner | Users can add data to a scatterplot and then try to draw the regression line, guided by a bar display that shows how much error the user line has. more |
|
| Regression Applet | Statistical Java (Dorai-Raj, Anderson-Cook, Robinson) | Creates sample data with user specified slope and intercept, users try to position the "best" line, guided by a display that shows the error of the current line as well as the least squares line, with option to display actual regression line. more |
|
| Visual Fit | Taur, McCulloch | Generates samples of data displayed on scatterplot, user tries to position the "best" line, guided by a display that shows the error, options to display actual regression line and population line, nonlinear models also available. more |
|
| Regression by Eye | Rice Virtual Lab in Statistics (Lane) | User attempts to draw regression line and guess correlation coefficient of random data sets based on scatterplots and MSE of their line compared to minimum before applet reveals answers. more |
|
| Interactive exercise on linear regression and analysis of variance | Economics Home Page, Univ. of Michigan-Dearborn | Walks through process of evaluating user's estimate of best line through three points and comparing to best fit line using SSE, SSR, and r squared. more |
|
| Simple Regression Applet | Seeing Statistics (McClelland) in Just the Essentials of Elementary Statistics (Johnson, Kuby) | User tries to position the "best" line through a data set, guided by a display that shows the error. more |
|
| Linear Regression | Java Demos for Probability and Statistics (Stanton) | Draws regression line as users place points on a plot, shows residuals, sample statistics, coefficient estimates, confidence intervals, ANOVA table, and visual representation of confidence and prediction bands. more |
