Understanding Regression Analysis

Regression analysis is a powerful statistical method used worldwide to examine relationships between variables. This online regression calculator provides accurate calculations following international standards from organizations including the American Statistical Association and World Health Organization statistical guidelines.

  • Linear regression models straight-line relationships between two variables
  • Polynomial regression fits curved relationships for more complex patterns
  • Exponential regression models growth or decay processes
  • Logarithmic regression describes diminishing returns patterns
