From the evidence, I can see the dataset has 8 rows with 16 columns, many of which are VARCHAR type with mixed/messy values. I'll write SQL to compute correlations between numeric-castable columns and examine co-occurrence patterns for categorical columns. First, let me identify which columns can be treated numerically and compute correlation coefficients between them, then look at categorical associations.",
