Regression Analysis

  • Regression analysis: A collective name for techniques for the modeling and analysis of numerical data consisting of values of a dependent variable (also called response variable or measurement) and of one or more independent variables (aka. explanatory variables or predictors)
  • The parameters are estimated so as to give a "best fit" of the data
  • Most commonly the best fit is evaluated by using the least squares method, but other criteria have also been used
  • Used for prediction (including forecasting of time-series data), inference, hypothesis testing, and modeling of causal relationships
