Least Squares graphing app
VVI has unveiled Least Squares, a math application that computes and displays linear regression. Users can input a variety of data points and the software will compute and draw a line on a graph to fit the data. The company says Least Squares uses a "concise and elegant" interface that can be used to teach linear regression, or as a professional tool for data exploration.
The application allows users to directly input data, or import it from databases and other sources. Least Squares is a free application based on Vvidget Code, which allows developers to create their own graphing applications. Vvidget Code is available to educational users for $80 and to commercial users for $180.
