Table 1

Linear correlation coefficients between the MAPE and COD values obtained from the 433 municipalities where the valuations and population sizes (inhab.) and sample sizes (N) of said municipalities have been calculated.

Technique
Correlation coefficient	Decision tree	Bagging	Boosting	Random forest
MAPE vs inhab.	0.10	−0.07	−0.04	−0.07
MAPE vs N	0.26	−0.03	0.02	−0.04
COD vs inhab.	0.09	−0.07	−0.03	−0.06
COD vs N	0.24	−0.02	0.03	−0.03
