Mini-Application Project Regression Analysis Introduction in statistics, regression analysis is the process of estimating the relationship among variable quantities [1]. These quantities are usually measured as data. One common form of regression analysis is to try and fit a function (to predict the values) to the data. In particular, linear regression tries to fit a linear function (line) to the data. This is usually done by minimizing the error between the data values and the predicted linear functional values. Background Given a data set that relates two quantities x and y, we can plot the corresponding ordered pairs (x,y) in the Cartesian plane to examine the data for tends. For example, consider the following plot (called a scatter plot)
