The figure below is the histogram of my data:
I want to check that whether the distribution of my data can be a skewed normal distribution or not.
I have already calculated the mean and standarad deviation of the data, and giving those parameters using "cdf" and a normal distribution:
test_cdf = [negativeData',cdf('Normal',negativeData',mu,sigma)];h = kstest(negativeData','CDF',test_cdf)
"kstest" rejects the null hypothesis, resulting in h=1.
Would you help me with defining a skewed test_cdf that fits the shape of the data's histogram better?
