Least Squares — Line Fitting - 1.0

Least Squares accepts data points and computes a line fit to that data (linear model, linear regression analysis) and shows it on a graph. Features:

• Least Squares has a concise and elegant user interface that shows how a focused single-purposed application can be used to learn about regression and also efficiently explore data sets. In other words, because of its elegance it can be used as a teaching tool for regression and as a precise and professional data exploration tool.
• With the Export Button, Least Squares' scatter and line fit graph appears in a powerful layout application for publication ready results.
• Vvidget Code includes the Least Squares Xcode project source code which can be used as a starting point for your own data analysis applications. Data entry can come from sources other than the user interface, such as a database, flat files, algorithms and instrumentation.
