Help in customising the NLS function to spit out mean and SD of new fit!!
...l ~ 1/sqrt(2 *pi)*std)*2.71828^2/(2*std4^2)),data=answer,start=list(std4=std4,sm=sm))
in the formula mean was mid point of 1st frequency bar and sd was sd of 6000 values.I do this 5 times each time changing the mean in the formula to be the mid point of the next frequency bar.
now i plotted plot(fittedvals ~trimmedvals)
I am told to plot experimental vs theoretical vlaues from the histogram and get a non linear least square curve fit.
I need the mean and sd of this new fit to proceed to my next module.I'm not sure if i'm on track. Excuse me if this sounds too naive.If nls is not what i...
