Hi guys,

I am trying to plot RMSE, rsquared and qqplot, but I keep getting error,

'undefined function or variable RMSE'

I am currently using 2017 MATLAB version

Which kind of regression model?

And if you have fitted data and true data, you can use minus to calculate the error, then use sqrt(mean(err^2)) which is what RMSE stands for.
