If I have a dataset of (50 000 events) of magnitude that range between 2 to 7. So 50 000 events that can have values between 2 to 7. I want to plot a cumulative histogram or scatter plot and then perform a regression analysis on the data. Can someone please explain as to how I can extract the frequency of events (for the Y axis) and how I can use the curve fitting toolbox to do this.
I do not understand what the "Weights" section refers to in the curve fitting toolbox.
