Workflow

  1. Data Import — upload a CSV/Excel file or load iris, mtcars, or Titanic from the built-in examples.
  2. Preprocessing — handle missing values, remove duplicates, scale numeric columns, and encode categorical variables.
  3. EDA — explore distributions, correlations, and run normality tests with interactive Plotly charts.
  4. Regression — choose from 8 algorithms, tune hyperparameters, view metrics (RMSE, MAE, R², Adj-R², MAPE, AIC, BIC), and inspect diagnostic plots including interaction effect visualisations.
  5. Classification — train classifiers, evaluate with ROC curve and confusion matrix, and inspect variable importance.
  6. Clustering — run K-Means, Hierarchical, or DBSCAN clustering, then visualise results with elbow plots, silhouette analysis, and cluster profiles.
