in his book A brief history of timeStephen Hawking describes his struggle to explain relativistic physics without using a single equation.
His editor had literally warned him in these words: Every equation you use will cut your readership in half.
Faced with the vivid possibility of near-zero sales, Hawking published A brief history of time with exactly one equation: E = mc².
The book sold 25 million copies, an astonishing achievement by any measure.
If Professor Hawking, even for the most pressing needs, had included the formula for Angler Information In your book, the sales figures might have been fascinating for an entirely different reason.
Because here lies, in its exquisitely inscrutable glory, the Fisher Information formula:
Compare, if you like, the notational nightmare shown above with E=mc².
To add to the confusion, the formula above comes with the following chewy definition:
Given a random variable unknown with a probability distribution f(unknown | θ), Fisher information…
