Test if a data distribution follows a Gaussian distribution in MATLAB

Question

I have some data points and their mean point. I need to find whether those data points (with that mean) follows a Gaussian distribution. Is there a function in MATLAB which can do that kind of a test? Or do I need to write a test of my own?

I tried looking at different statistical functions provided by MATLAB. I am very new to MATLAB so I might have overlooked the right function.

cheers

Answer 1

Check this documentation page on all available hypothesis tests.

From those, for your purpose you can use:

• Chi-square goodness-of-fit test
• Lilliefors test
• z-test
• t-test
• Kolmogorov-Smirnov test

... among others

You can also use some visual tests like:

• hist
• normplot
• cdfplot
