Fit Nonlinear Model to Data with Excel

This tutorial guides users through importing heart rate data into Excel, preparing it for analysis, and constructing a regression model. It covers plotting data, adjusting model parameters, and using Excel Solver to optimize the fit. The tutorial concludes with calculating statistics like R-squared to evaluate the model's accuracy.
