Fisher information tells us how much information about an unknown parameter we can get from a sample. In other words, it tells us how well we can measure a parameter, given a certain amount of data. More formally, it measures the expected amount of information given by a random variable (X) for a … See more Finding the expected amount of information requires calculus.
