Is a generic regression example and can be used in all industries and disciplines
Uses the PTC Mathcad "regress" function to fit a plane through a set of 3D (x, y, and z) data
This worksheet using PTC Mathcad software provides you with a sample data set that then shows you how to create a matrix containing the x and y coordinates of the data set using the augment function. It also shows you how to perform a regression on the data using the "regress" functions and the following arguments
1. A matrix containing the x and y coordinates of the data set
2. A vector containing the z coordinates of the data set
3. The power of the fit for a plane, the power is 1
The worksheet then shows you how you might graph the plane and the data set using PTC Mathcad software. This worksheet provides you with step by step instruction, sample, data, and solutions to aid you.
