Master Multivariate Regression Analysis with AI
Build sophisticated statistical models that uncover complex relationships in your data. From simple linear regression to advanced multivariate modeling, get AI-powered insights in minutes, not hours.
Picture this: You're analyzing customer behavior data with dozens of variables—demographics, purchase history, seasonality, marketing touchpoints. Traditional tools force you to juggle multiple software packages, write complex code, or settle for oversimplified models. But what if you could build sophisticated multivariate regression models as easily as writing a sentence?
Multivariate regression analysis reveals how multiple independent variables simultaneously influence your dependent variable. Unlike simple regression that examines one relationship at a time, multivariate analysis captures the complex web of interactions that drive real-world outcomes. With Sourcetable's AI-powered analysis, you can build these models instantly and interpret results in plain English.

Interactive Visualization
Explore relationships with dynamic 3D plots, coefficient forests, and prediction intervals that update as you adjust model parameters.
Rapid Iteration
Test different model specifications, compare performance metrics, and refine your analysis in real-time without wrestling with syntax or code.
Multivariate Regression in Action
See how different industries leverage multivariate regression to solve complex business problems and drive data-driven decisions.
Pricing Strategy Optimization
A major retailer used multivariate regression to understand how price, competitor pricing, inventory levels, and seasonal trends jointly influence demand. The model revealed that a 5% price reduction during low-inventory periods actually decreased profits by 12%, leading to a dynamic pricing strategy that increased margins by 18%.
Employee Performance Prediction
An HR analytics team built a model predicting employee performance using education level, experience, training hours, team size, and management style. They discovered that team composition mattered more than individual credentials, reshaping their hiring and team-building strategies.
Medical Treatment Effectiveness
Healthcare researchers analyzed treatment outcomes using patient age, comorbidities, treatment intensity, and hospital characteristics. The multivariate model identified that hospital volume and patient age interaction was the strongest predictor of success, informing referral protocols.
Marketing Mix Modeling
A consumer goods company analyzed how TV advertising, digital spend, promotions, and seasonality drive sales across different regions. The model showed that digital advertising had 3x higher ROI in urban markets, while TV dominated rural areas, optimizing budget allocation.
Real Estate Valuation
Property valuers use multivariate regression with square footage, location scores, age, amenities, and market conditions to predict home values. The model accounts for complex interactions like how proximity to schools affects value differently in various neighborhoods.
Supply Chain Optimization
A manufacturing company modeled delivery times using distance, traffic patterns, weather, driver experience, and vehicle type. They found that driver experience reduced weather-related delays by 40%, leading to targeted training programs and route optimization.

Robust Regression Options
Handle outliers and non-normal errors with robust regression techniques. Get reliable results even when your data violates standard assumptions.
Time Series Integration
Combine regression with time series components to model trends, seasonality, and lagged effects in longitudinal data analysis.

Frequently Asked Questions
How does Sourcetable handle multicollinearity in multivariate regression?
Sourcetable automatically detects multicollinearity using variance inflation factors (VIF) and correlation matrices. When high correlations are found, the AI suggests remedial actions like variable removal, principal component analysis, or ridge regression. You'll get clear warnings about which variables are problematic and recommendations for model improvement.
Can I perform hierarchical or nested regression analysis?
Yes! Sourcetable supports hierarchical regression where you can build models step-by-step, adding variable blocks and comparing model improvements. The AI automatically calculates R-squared changes, F-statistics for model comparisons, and helps interpret the incremental contribution of each variable set.
What sample size do I need for reliable multivariate regression results?
Sourcetable provides automatic sample size guidance based on your number of predictors and desired effect sizes. Generally, you need at least 10-15 observations per predictor variable, but the AI considers your specific context and warns about potential power issues or overfitting risks.
How does the AI handle categorical variables in regression models?
Categorical variables are automatically encoded using appropriate methods (dummy coding, effect coding, or contrast coding). The AI selects the best reference category and explains the interpretation of each level's coefficient. You can also specify custom contrasts for more sophisticated comparisons.
Can I validate my models with cross-validation or hold-out samples?
Absolutely! Sourcetable includes built-in cross-validation, train-test splits, and bootstrap validation. The AI automatically assesses model generalizability and provides metrics like cross-validated R-squared, prediction intervals, and model stability measures.
What diagnostic plots and tests are available for assumption checking?
Sourcetable generates comprehensive diagnostic plots including residual plots, Q-Q plots, leverage plots, and Cook's distance measures. Statistical tests for normality, homoscedasticity, and linearity are performed automatically, with clear explanations of what violations mean for your conclusions.
How do I interpret interaction effects in multivariate models?
When interaction terms are included, Sourcetable provides intuitive visualizations showing how the effect of one variable changes across levels of another. You'll get simple slope analyses, regions of significance, and plain English explanations like 'The impact of price on demand is stronger for premium customers than budget shoppers.'
Can I export my regression models for use in other systems?
Yes! Export your models as equations, prediction functions, or in formats compatible with other software (R, Python, Excel). You can also generate automated reports with model summaries, assumption checks, and business interpretations ready for stakeholder presentations.
