Hello Service Team,
I fitted my XY data with a trimodal normal distribution using the multiple peak fit under the analysis tab and I am trying to understand the summary parameters. Assuming xc is the mean, is the standard error reported next to it the standard deviation or the standard error of the mean? I assume it's the former since there is no repeated sampling in this case, or is the system estimating the standard error based on the number of iterations done to reach the Chi-Sqr tolerance value? Also, what does W stand for?

Hello Team,
This is a follow-up message to my previous request. In the figure below, the red curve appears as a normal distribution so it's reasonable to apply a Gaussian fit, but what about the green and blue curves which appear left skewed? Is it still OK to use the Gaussian fit values for them and rely on the reported values? Or is there a way to apply non-linear fitting to a trimodal distribution like this that has seem to have a mix of Gaussian-type and left-skewed-type functional behaviors?
Please advise.
