Correlations among continuous variables are Pearson correlations; correlations among categorical variables are phi coefficients, and correlations between continuous and categorical variables are point-biserial correlations. For the purposes of the correlation matrix, cannabis use was treated as a continuous variable, although it is treated as an ordered categorical variable in regression analyses.
