How does the Moment Generating Calculator work?

M(t) = E(e^(tX)) where t = parameter Then: Moments: mean = M'(0), variance = M''(0) - [M'(0)]² Then: Each MGF unique to distribution Then: MGF determines distribution uniquely.

Can you give an example of how to use the Moment Generating Calculator?

Example: Input Distribution params gives a result of MGF function.

Is the Moment Generating Calculator free to use?

Yes — completely free with no registration, download, or subscription required. All calculations happen instantly in your browser.
