Calculate Pearson, Spearman, and Kendall correlation coefficients with statistical significance testing and comprehensive analysis
Pearson Correlation: Assumes linear relationship and normally distributed variables. Sensitive to outliers
Spearman Correlation: Non-parametric, works with any monotonic relationship. Good for ordinal data
Kendall Tau: More robust to outliers than Spearman, preferred for small samples or when ties are present
P-value: Approximate values for hypothesis testing. Lower p-values indicate stronger evidence against null hypothesis (no correlation)
