An RSS feed takes the headlines, summaries, and update notices, and then links back to articles on your favorite websites page. This content is distributed in real time, so that the top results on the RSS feed are always the latest published content for a website.
How does RSS and blogging work?
RSS is a type of web feed that allows users and applications to receive regular updates from a website or blog of their choice. RSS allows bloggers and publishers to automatically syndicate their content, so that people can read it in their email, feed reader and other devices.
The residual sum of squares (RSS) measures the level of variance in the error term, or residuals, of a regression model. The smaller the residual sum of squares, the better your model fits your data; the greater the residual sum of squares, the poorer your model fits your data.
The residual sum of squares can be zero. The smaller the residual sum of squares, the better your model fits your data; the greater the residual sum of squares, the poorer your model fits your data. A value of zero means your model is a perfect fit.
