Goodness-of-Fit Measures We will introduce three measures to judge how well the 
sample regression fits the data. 
1. The Standard Error of the Residual (Estimate). 
2. The Coefficient of Determination (R^2) 
3. The Adjusted R^2 
Mean Squared Error To compute the standard error of the residual, we first compute 
the mean squared error. 
- we first compute the error sum of squares 
- dividing SSE by the appropriate degrees of freedom, n-k-1, yields the mean squared error,

Linearity/Mean zero assumption - Means that the expected value (deviances) of errors is zero. 
This leads to difficulties in estimating B0 and means that our model does not include a necessary 
systematic component 
Constant variance assumption - Means that it cannot be true that the model is more accurate for 
some parts of the population, and less accurate for other parts of the populations. This can result in less 
accurate parameters and poorly-calibrated prediction intervals.

The number of degrees of freedom of the χ 2 (chi-square) distribution for the pooled variance estimator 
is N − k + 1 where k is the number of samples. - False 
If the confidence interval for a regression coefficient contains the value zero, we interpret that the 
regression coefficient is definitely equal to zero. - False. The coefficient is plausibly zero, but we 
cannot be certain that it is
