*using an Excel addon
Great nonetheless, and not to take anything away from the project, but I guess what I was expecting from the title, however ambitious, was an Excel-native solution.
- im_down_w_otp 5y agoBlargh. Me too. I was really hoping this was a deep-dive into an incredible, if beautifully deranged, misuse of Excel.
- nerdponx 5y agoI've heard legends of people fitting shallow feedforward NNs with pure Excel formulas. I once interned for an economist who was using recursive Excel formulas for some kind of iterative optimization algorithm. I don't remember what it was, probably some iterative least squares thing. I also was a research assistant for an economist who fit linear regressions with hand-written routines in Matlab. For some reason they felt more comfortable using Matlab's QR decomposition instead of just using the built-in linear modeling tools in R or even Stata. Some people just want to use their favorite tool even if it makes no sense to do so.
- 7thaccount 5y agoDoesn't Matlab fit equations like that easily in a built-in fashion? Why use hand written routines?
- nerdponx 5y agoI had that thought as I was writing this post. I have no idea.
