Abstract

The objective of this work was to adjust a distribution to the IGPM12 data and estimate the probability of this index assuming certain values that may be specific to individuals, legal entities and investors who have commitments or financial investments whose investors are linked to the IGPM. To choose between the normal, Cauchy, logistic and LS t-Student distributions, the Kolmogorov-Smirnov test and the Akaike Information Criterion (AIC) were analyzed. The LS t Student model with parameters mean 7.29, standard deviation 3.99 and nu 2.20 was selected and with it the probabilities of interest were estimated. It is concluded that the most likely scenario (p = 62%) involves an adjustment of this index between 0% and 10% for the next 12 months.
