Webb3 jan. 2024 · So why maximum likelihood and not maximum probability? Well this is just statisticians being pedantic (but for good reason). Most people tend to use probability and likelihood interchangeably but statisticians and probability theorists distinguish between the two. The reason for the confusion is best highlighted by looking at the equation.

Probability theory is the branch of mathematics concerned with probability. Although there are several different probability interpretations, probability theory treats the concept in a rigorous mathematical manner by expressing it through a set of axioms. Typically these axioms formalise probability in terms of a probability space, which assigns a measure taking values between 0 and 1, ter…
In science, the probability of an event is a number that indicates how likely the event is to occur. It is expressed as a number in the range from 0 and 1, or, using percentage notation, in the range from 0% to 100%. The more likely it is that the event will occur, the higher its probability. The probability of an … Visa mer When dealing with experiments that are random and well-defined in a purely theoretical setting (like tossing a coin), probabilities can be numerically described by the number of desired outcomes, divided by the total … Visa mer The scientific study of probability is a modern development of mathematics.
