Local Regression for Country Data
Local Regression for Country Data
This Demonstration studies pairwise relationships between properties of countries. A total of 124 properties can be studied. The figure on the left gives the scatter plot of the points. It also gives a local regression curve that is calculated with the so-called loess method [1]. The local regression curve describes the trend of the data, thus giving a guide to infer the nature of the relationship between the two properties. The figure on the right gives the residuals of the regression together with a local regression curve to the residuals. This figure gives information about the quality of the local regression curve shown in the left figure: the closer the local regression curve of the residuals is to zero, the better the local regression curve fits the data.
