File:HeightWeightExample.WrongConversion.Quadratic.Residuals.png
Summary
| Description |
English: In Linear regression the example data gives heights in metres, but the original values were inches, and the conversion was bungled. The plot of weight vs. height shows odd horizontal spacing, and the quadratic fitted to the data produces these residual values y(i) - f(x(i)). |
