How to calculate MSE for Gaussian histogram?

12 views (last 30 days)
I fit the Gaussian distribution with the histfit command. I want to calculate MSE but I have no idea how to do it.
Can this approach be used for MSE calculate?
hhf = histfit(noise_filt)
df = fitdist(noise_filt(:), 'Normal')
y = normpdf(hhf(1).XData,df.mu,df.sigma);
mse = mean((y - hhf(1).YData).^2)
mse = 1.183472134374673e+07

I'd probably do it on the original data, not the histogram
meanValue = mean(noise_filt);
mse = mean((noise_filt - meanValue) .^ 2)

I don't see why not. The MSE doesn't care what produced the reference and test data.
