Ordinary Least Square. OLS is a technique of estimating linear relations between a dependent variable on one hand, and a set of explanatory variables on the other. For example, you might be interested in estimating how workers’ wages (W) depends on the job experience (X), age (A) and education level (E) of the worker. 10.2.2 Non-Constant Variance. A second thing to look for in visual diagnostics of residuals is non-constant variance, or heteroscedasticity.In this case, the variation in the residuals over the range of predicted values for \(Y\) should be roughly even. A problem occurs when that variation changes substantially as the predicted value of \(Y\) changes, as is illustrated …YouTube Star #9 19 Year Old #2 Born in Ohio #1 Aquarius #3 IShowSpeed Is A Member Of .
