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.
Thread: R-squared value meaning. I have a bunch of charts with 6 months of data in each (JAN - JUN). Some of the charts show R-squared values for my trendlines with a value nearing 1.0. That's great. However some have very low values on the order of 0.2 or 0.3. I'm not good at math but shouldn't they all have high values if they all have 6 months of data each?
