Introducing Local Regression Studio

---

Local Regression Studio is a browser-based regression modeling workspace designed to help users build, compare, validate, and apply regression models directly on their own device. It provides a guided workflow for importing CSV data, selecting target and feature variables, preparing data, training models, reviewing results, and generating predictions.

The studio is designed around a local-first workflow. Your data is processed in the browser, so you can explore models and generate predictions without uploading your dataset to a remote server.

Local Regression Studio is a practical machine-learning tool for continuous numeric prediction problems. It helps users answer questions such as:

• Can I predict a material property from process variables? 
• Can I estimate a performance metric from experimental inputs? 
• Which regression model works best for my dataset? 
• How reliable are my predictions? 
• Can I apply a validated model to new unknown data?

It is intended for regression tasks where the output is a number, such as strength, cost, yield, temperature, response time, concentration, efficiency, or another measured continuous value.

• Browser-based and local-first
  Run the workflow directly in your browser. No server upload is required for normal use. 
• CSV data import
  Load tabular data and select target and feature columns through a guided interface. 
• Data preparation tools
  Handle numeric and categorical inputs, missing values, scaling, encoding, target transformations, and train/validation/test splitting. 
• Multiple regression models
  Train and compare models such as linear regression, ridge regression, elastic net, robust regression, decision trees, random forests, gradient-boosted trees, k-nearest-neighbour regression, Gaussian-process regression, quantile regression, and neural-network regression. 
• Model comparison and validation
  Compare candidate models, review performance metrics, inspect diagnostic plots, check grouped performance, and apply acceptance criteria before using a model operationally. 
• Uncertainty-aware prediction
  Use supported models and workflows to estimate prediction uncertainty and review prediction intervals where available. 
• Prediction for new data
  Import new unknown CSV data and generate downloadable prediction results. 
• Governance and export tools
  Save model files, project records, validation reports, approval records, metrics, split predictions, and approved prediction packages. 
• Static-site deployment
  The studio can be hosted as a static website, including on GitHub Pages.

Local Regression Studio is useful for:

• Researchers who need a practical tool for exploring regression relationships in experimental or simulation data. 
• Engineers who want to predict performance, properties, process outcomes, or design responses from tabular data. 
• Data scientists who need a lightweight local workflow for quick regression modeling, validation, and prediction. 
• Students and educators who want a hands-on regression modeling environment without setting up Python or server infrastructure. 
• Technical teams who want a privacy-conscious tool for local model review, approval, and prediction workflows.
