Table 8 - Independent variables for the Linear Model
.
To check whether the model is not biased and if it is a fair model for
scoring purposes, one can analyze the relationship between the predicted
and the actual value of EUI. The residual plot can also uncover eventual
patterns that would indicate a biased model, i.e. a model that needs
other features or degrees of freedom in order to adequately estimate the
dependent variable. The reason to plot the logarithm instead of the
original purely for visualization purposes, since the logarithm of EUI
is closer to a normal distribution. From the residual plots we can see
that the residual (predicted value - actual value) is not biased.
