Important detail:All the covariates are binary variables.Considering that when both(2) variables are dichotomous, a Pearson correlation coefficient is equivalent to the phi coefficient and to Spearman coefficient,would not be wrong write in the statistical analysis text(topic) that multicollinearity was conducted using spearman correlation or I have to change the words “spearman correlation” to “Phi coefficient”(in the text) to be 100% correct in terms of methodology description.?
