Pick 4 — Oregon Lottery
Pair frequency analysis for Oregon Pick 4 tracks which two-digit pairs appear together most often. With four positions producing six pairs per draw, patterns accumulate more quickly than in Pick 3.
The top 20 pairs table shows the most frequent combinations. The heatmap gives a visual overview of all 55 unique pairs (10x10 grid). Darker cells indicate higher co-occurrence. Compare with individual digit frequency to distinguish true pair strength from individual digit popularity.
High pair frequency primarily reflects individual digit frequency, not a special pairing relationship. Use pair data as supplemental information, not a primary selection strategy.
