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.
Low R-squared values in multiple regression analysis? In my regression analysis I found R-squared values from 2% to 15%. Can I include such low R-squared values in my research paper? Or R-squared values always have to be 70% or more. If anyone can refer me any books or journal articles about validity of low R-squared values, it would be highly appreciated.
