I have some data that I want to divide into a training set and a validation set in order to do linear regression on the training set to find y0 and r. The training set should contain at least 50% of the data. My code so far is that below:
A=[130, 300, 400, 500, 650, 1075, 2222, 2550, 3300]';
t = [1930, 1943, 1966, 1976, 1991, 1994, 2000, 2005, 2008];
If I can assume the function is exponential and is y(t)= y0*e^rt how do I continue to plot the training set to find y0 and r?
Thankful for all help!
