Now if you really are doing a true nonlinear fit and you have this heteroscedasticity going on then you can write a bootstrap resampling (with replacement) simulation - idk how to do this in Excel but probably needs VBA- basically resample the data with replacement, compute the prediction, and do this a large # of times then take the 2.5% and 97.5% percentiles. And in addition does it result in approximate linearity on the log scale?īecause in that case its technically still linear regression OLS and it becomes much easier even in excel to obtain CIs of coefficients and prediction intervals via standard OLS (and not nonlinear regression-formulas) When you log transform the Y does it at least solve the variance increasing problem- I suspect it might. Well its going to be tricky to do this in Excel honestly. R-bloggers - blog aggregator with statistics articles generally done with R software.
