Frequently Asked Questions

What is a multiple regression calculator?
A multiple regression calculator is a statistical tool that analyzes the relationship between one dependent variable and two or more independent variables. It helps predict outcomes and understand which factors most influence results.
How accurate are multiple regression calculations?
Accuracy depends on data quality, sample size, and model specification. Most calculators provide R-squared values showing what percentage of the dependent variable’s variation is explained by the independent variables.
Can I use this calculator for medical or financial decisions?
This calculator provides statistical estimates only. For medical, financial, or legal decisions, consult appropriate professionals. Statistical results should inform but not replace expert judgment.

Regression Results

Your multiple regression analysis results will appear here after calculation. The calculator uses standard ordinary least squares (OLS) methodology.

Results are based on statistical estimation. Consider confidence intervals and p-values when interpreting coefficients.

Regression Equation

Interpretation Guidance

When interpreting your multiple regression results:

  • R-squared: Higher values (closer to 1) indicate better model fit
  • Coefficients: Represent change in Y per unit change in X, holding other variables constant
  • p-values: Values below 0.05 suggest statistically significant relationships
  • Confidence intervals: Provide range of plausible values for coefficients
