... For data set #2, a quadratic function would clearly provide a much better fit. For data set #3, the relationship is perfectly linear except one outlier, which has obviously greatly influenced the fit even though its x value is not unusually large or small. The signs of the residuals here (correspond ...

... Dummy-Variable Models (more than 2 Levels) The number of dummy variables is one less than the number of levels Example: Y = house price ; X1 = square feet If style of the house is also thought to matter: Style = ranch, split level, condo Three levels, so two dummy variables are needed Advanced ...

Simple Linear Regression
... the smallest RSS from all possible candidate lines b0 + b1 x. This smallest RSS indicates that the correspondence between the data and the fitted line is as good as it can possibly be. This line is known as the least squares regression (LSR) line,4 and the estimates of the intercept and slope obtain ...

The coefficient of variation should only be computed for continuous data •A given standard deviation indicates a high or low degree of variability only in relation to the mean value •It is easier to g ...
