Hello everyone,
I have a histogram distribution of my data set.
Then I have fit the histogram distribution with gaussian using the cghistoplot.
But in my 12 data set 8 data set fits well with single gaussian, but other four seems to be like it has to be fit with a double gaussian. So please let me know how to fit the histogram distribution with a double gaussian.
Is there any routine to do this.
thanking you in advance
sid
