The explicative relationships between the variables were studied with a binary logistic regression model, since the dependent variable (performance) is a dichotomic variable
Border Dummy is a dichotomic variable
that takes the value of one if the countries share a common border, zero otherwise.
The correlations between the predictor variable and the dependent variables were analyzed, using Pearson's correlation coefficient for quantitative variables and the point-biserial correlation coefficient for dichotomic variables
All these were coded as dichotomic variables
, being scored with 0 or 1 point, depending on their absence or presence.

We used the coding method "parameterization of reference cell" to code the dichotomic variables
, assigning the value (0) to the categories Female (Sex), Medicine /High School), Public (Middle School Teaching Institution) and Montevideo (Location), and the value (1) for the categories Male, Engineering, Private and Inland.
