Story 4.1: Configuration de la Régression

Status: review

Story

As a Julien (Analyst), I want to configure the parameters of my regression model, so that I can tailor the analysis to my specific hypothesis.

Acceptance Criteria

1. Model Selection: Users can choose between "Linear Regression" and "Logistic Regression" in the sidebar.
2. Dynamic Validation: The system checks if the Target Variable (Y) is compatible with the selected model (e.g., continuous for Linear, binary/categorical for Logistic).
3. Parameter Summary: The sidebar displays a clear summary of the selected X variables and the Y variable before launch.
4. Interactive Updates: Changing X or Y variables updates the "Implementation Readiness" of the model (enable/disable the "Run" button).

Tasks / Subtasks

• UI Enhancements (AC: 1, 3)
  • Add model type dropdown to AnalysisConfiguration.tsx.
  • Implement a "Selected Features" summary list.
• Validation Logic (AC: 2, 4)
  • Implement frontend validation to check if the target variable matches the model type.
  • Disable "Run Regression" button if validation fails or selection is incomplete.

Dev Notes

• Validation Rules:
  • linear: Cible doit être de type numeric.
  • logistic: Cible doit être categorical ou boolean.
• UI: Added a toggle switch for model selection and refined the predictor selection list with importance bars.

Project Structure Notes

• Modified frontend/src/features/analysis/components/AnalysisConfiguration.tsx.
• Updated frontend/src/store/use-grid-store.ts with ModelType state.
