Curriculum Module
Created with R2020a. Compatible with R2020a and later releases.

Description

This package contains a live script and supporting files to illustrate some basics of regression analysis. The materials are designed to be flexible and can be easily modified to accommodate a variety of teaching and learning methods. We include a brief background, interactive illustrations, tasks, reflection questions, a real-world application example, and a guided exercise for the different concepts explored.

The instructions inside the live scripts will guide you through the tasks and activities one section at a time. To run this interactive script in a controls-only mode, use the Hide code button on the View tab of the MATLAB toolstrip.

Learning Goals

  • Explain the difference between linear, multiple linear, and nonlinear regression.
  • Use ordinary least squares to analytically solve for linear regression parameters.
  • Assess and improve the performance of a regression model using a goodness-of-fit measure.
  • Apply gradient descent to iteratively minimize a cost function and estimate model parameters.
  • Explain the effect of increasing and decreasing the learning rate and number of steps for the gradient descent algorithm.
  • Use a linear regression model to perform short-term forecasting.
