📊 Data Quality Overview
🔧 Handle Missing Values
🔁 Convert Numerical to Categorical
Create categorical bins from numeric columns (e.g., age groups, risk levels).
3 Configure Analysis
Mean, median, mode, SD, Z-scores, skewness, kurtosis, normality test.
Parametric two-sample comparison. Includes Shapiro-Wilk normality check.
Parametric comparison of 2+ groups. Includes Tukey HSD post-hoc.
Non-parametric alternative to t-test.
Non-parametric alternative to ANOVA.
Kaplan-Meier curves with log-rank test.
Binary outcome regression with odds ratios.
Pearson & Spearman correlation. Correlation does NOT imply causation.
Linear regression with validity checks.
Cronbach's alpha, split-half reliability, item-total correlations.
Chi-Square test of independence for categorical variables.
Paired t-test for comparing two related measurements.
Two-way ANOVA with interaction effects.
Analysis of covariance — ANOVA with a continuous covariate.
Multivariate ANOVA for multiple dependent variables.
Non-parametric paired comparison (alternative to paired t-test).
Non-parametric repeated measures test (alternative to repeated ANOVA).
McNemar's test for paired binary data (before/after).
ROC curve and AUC for diagnostic/classification performance.
Bland-Altman analysis for method agreement.
Sensitivity, specificity, PPV, NPV, LR+, LR− for diagnostic tests.

Dose-response curve fitting (4PL or log-linear).
Principal Component Analysis for dimensionality reduction.
Exploratory Factor Analysis with varimax rotation.
Cluster analysis (K-Means or Hierarchical).
Stepwise regression with forward/backward/both selection.
Cohen's Kappa for inter-rater agreement (categorical).
Intraclass Correlation Coefficient for rater reliability.
Shapiro-Wilk, Anderson-Darling, Lilliefors, Jarque-Bera normality tests.
Statistical power and required sample size calculation.
Meta-analysis (DerSimonian-Laird) with fixed and random effects.
