See: Parameter. Second pass regressionSecond pass regressionA cross-sectional regression of portfolio returns on betas. The estimated slope is the measurement of the reward for bearing systematic risk during the period analyzed. RegressionRegressionA mathematical technique used to explain and/or predict. The general form is Y = a + bX + u, where Y is the variable that we are trying to predict; X is the variable that we are using to predict Y, a is the intercept; b is the slope, and u is the regression residual. The a and b are chosen in a way to minimize the squared sum of the residuals. The ability to fit or explain is measured by the R-square. Regression analysisRegression analysisA statistical technique that can be used to estimate relationships between variables. Regression analysisRegression analysisAnalysis which examines the correlation between two or more variables in a mathematical model and attempts to prove whether or not the past relationships will be the same in the future.
