Building a handrail for your deck may seem like a simple task. In many cases it is -- until the time arrives to figure out how to get the balusters or spindles evenly spaced along the handrail. Evenly spaced spindles improve the symmetry of the rails and lend a professional look to the project. But finding the right measuring formula may give the average home handyman pause.
R-squared is a statistical measurement that determines the proportion of a security's return, or the return on a specific portfolio of securities, that can be explained by variations in the stock market, as measured by a benchmark index.
Simply compare the adjusted R-squared values to find out! The adjusted R-squared is a modified version of R-squared that has been adjusted for the number of predictors in the model. The adjusted R-squared increases only if the new term improves the model more than would be expected by chance.onsequently, you donât want to include more terms in the model than necessary. (Read an example of using Minitabâs Best Subsets Regression .). Finally, a different use for the adjusted R-squared is that it provides an unbiased estimate of the population R-squared.
