Table 1.

Description of the models, which includes the model name, the mathematical formulation of the conditional probability for the different models, and the model parameters. It is possible to note that the models have a different number of parameters; the BIC method allows them to be compared on equal grounds [28].

M1		μ, σ
M2		β0, β1
M3		β0, β1
M4		α, β0, β1
M5		α, β0, β1
M6		β0, β1, β2
