Detects variable types (continuous, count, binary, ordinal, categorical), checks outliers, normality, latent normality, and linearity, and selects the appropriate correlation method for each pair. Supports 18 methods: Pearson, Spearman, Kendall's tau, point-biserial, biserial, rank-biserial, phi, tetrachoric, Yule's Q, polychoric, polyserial, Goodman-Kruskal's gamma, the correlation ratio (eta-squared), Kruskal-Wallis eta-squared, Freeman's theta, Cramer's V, Tschuprow's T, and Theil's U, each with a confidence interval and p-value. Explains the selection rationale in the output, follows tidy data principles, and works in both interactive and scripted workflows. The methodology is described in Harshvardhan and Ranjan (2026) <doi:10.48550/arXiv.2607.22285>.
