#2003 Leverage Effect
in Regression


This program visualizes the effects of outliers to regression lines. The user may pick up a point with the mouse and move it across the chart. The resulting regression line is automatically adjusted after each movement, showing the effect in an immediate and impressive way..... more

#2004 Error Surface of Linear Regression 

Linear regression can be seen as an optimization problem, searching for the lowest point of the error surface. This program allows to play with the error surface of a regression line and to find the optimum fit by intuitive means...... more

#2005 Distribution of the Correlation Coefficient 

The correlation coefficient is one of the commonly used statistical measures. Despite its frequent use, the fact that the correlation coefficient shows a broad distribution if too few observations are used is not wellknown....... more

#2006 Regression of Weakly Correlated Data 

There is a common mistake about the linear regression of xymeasurements with small or no correlation between them. This simulation tries to shed some light on this aspect of linear regression....... more

#2007 Time Averaging of Signals 

Signals below the detection limit cannot be measured without improving the signaltonoise ratio. This program shows the improvement of the SNR by accumulating signals....... more

#2010 Measures of
Location


This program shows the effects of individual data points on some univariate measures of location (mode, median, mean, and trimmed mean). The user may pick and move individual data points, watching the change of these measures...... more
