Using "Sweave" and "Latex" with the Monitor function

Finally I can find the best configuration for "Sweave" in "R" to generate the Validation Reports with the Monitor function. Still some more improvements are needed, but I am quite happy with the results.

 

 

 

 

Looking the Residual plot taking into account the Boxplot

I have improved the Monitor function just to give more importance to the Box plots. So we can see simultaneously the boxplot and the residual plots and to have more clear ideas about the performance of the model. I have more ideas coming so I hope to complete it in a future.

As we know the box plot give us the median and limits for the quartiles. It defines also the limits to consider where a sample is an outlier. So I divide the samples in 5 groups (Q1 to MIN,Q1,Q2,Q2 to MAX and BPOUT) depending of their value in the boxplot.

If the samples are ordered in the residual pot by their reference value we get:

It is important to order the data by date and we can get other conclusions:

Spending time looking to these plots we can get some conclusions to improve the model to make it more robust.
