  • What is the difference between a probability and a likelihood? Not much, it's just a shift of perspective!

    I’ve had 7 statistics courses at the graduate level, and no one has ever explained what likelihood is.
    Thank you.

    An Amazing video and explanation. All these other videos only said points on the probability density function are likelihood but it didn't make any sense to me. the way you explained it cleared everything.

    Even if the coin is not fair the probabilities still adds up to one.

    • @briangreco2718

      That is very true! Likelihoods of a single outcome under multiple probability distributions, however, do not add up to one.

    Great video! I'm just curious: When you say "we don't know which universe we're in," is this just another way of saying, "we don't know the probability distribution of the coin"?

    Amazing, if i got correctly its like In probability, we start with the whole and then delve into the details, but in likelyhood, we begin with the details and then move to the whole.

    • @briangreco2718
      @briangreco2718  Місяць тому +1

      Yup, in probability we start with the situation/universe/parameter and find the probability of outcomes. With likelihood, we start with the outcomes and try to figure out the situation/universe/parameters!

    Lately I've been introducing LRT, or tests in general, to my coworkers like "I would bet you with 1:20 odds that this coin is rigged, would you take this bet?"

      No worries, Martin - you only really need to know what "likelihood" is if you're doing advanced statistics stuff anyways. In everyday language, these words mean the same thing, and even in statistics, they are really not so different!

    I once flipped a nickel onto the floor, near a wall. It bounced off the floor, one-hopped the wall, and landed on the EDGE of the nickel.

    A Very nice explanation. We poor experimental physicists (and any other scientists whose discipline is base on observations) deal almost exclusively with likelihoods - we use observations to draw conclusions about the (a priori unknown) properties on the actual universe. Theoretical physicists, OTOH, postulate those properties and calculate probabilities of what we _should_ observe. Then we compare the two.
