Basic Probability: The Multiplication Rule

  • Опубликовано: 1 окт 2024
  • An introduction to the multiplication rule. (I assume the viewer has an understanding of conditional probability and independence, but I do a very brief review of those concepts.) I introduce the multiplication rule for two events, work through a simple example, then discuss the multiplication rule for 3 events and how it generalizes to any number of events. I end with an example using the multiplication rule to find the probability of a 3 way intersection.
    Canadian demographic information is based on Statistics Canada numbers found here:

    Hi. I need your help, can you help me, please?
    I watched your videos about linear regression, but these formulas are not working for me, let me explain. I am translating one python library to standard python. So when I tried to get t-value, from standard error of beta. I have zero intercept ordinary least square, and SE(b) should be s/sqrt(sum(x^2)), where s=sqrt( sum( resud^2 ) / (n-1) ) ( not -2 because of zero intercept )
    x = 1, 2, 3
    y = 7, 3, 5
    beta = 2
    s = 5.217
    sqrt(SSxx) = 374.165
    SE(b) = 1.394
    what I should get is (library's solution)
    Se(b) = 0.98
    Help me, please

    Hi
    Can you please upload code in R( without use of boot())
    for non parametric bootstrap confidence Interval for Binomial distribution to conduct inference on p. We could use phat= y/n
    For the bootstrap methods, use B = 200 resamples.
    N=1500 and p varies from 0.01 to 0.99 by 0.01

    Hello JB statistics. Thank you for your videos. I am a beginner student of statistics and find your videos really helpful. Is there an order for them from the start? if I'm to go through them to really get a grasp of it.PLEASE HELP

  • @scottmovold6086

    I'm quite certain that this incorrect. Given that these probabilities are not independent.

      Quite certain what is incorrect? And even without knowing what you're talking about, I'm very, very confident you are simply wrong.

    This is just what I needed... someone to slowly and carefully explain this looping situation, and that it can't be solved with just those two probabilities.

    Can you make a video on jointly distributed random variables in a continuous setting? I am struggling to understand this, and I would guess that is also true for many other people. I love your videos, and I hope you continue to make them!

      Thanks! And you are very welcome. I wanted to keep it all pretty straightforward, as it is aimed at students in an applied intro statistics class, but I also wanted to go a little beyond the basic urn and deck of cards problems.
