Will display the probability that 2 (two) or more successes will occur in a random experiment with distribution B(3.3). 343, and together with the probability for one success (.441) this will yield a cumulative value of. The probability for 0 (zero) successes is. In other words, Stata will render the value of the cumulative probability function. Will display the probability that 1 (one) or fewer successes will occur in a random experiment with distribution B(3.3). Stata will use floor(1.8) instead, that is, 1. Note that you may write dis binomialp(3,1.8.3), requesting the probability that you will observe 1.8 successes, which is impossible as the values of a binomial random variable are always integers. Will display the probability that exactly 1 (one) success will occur in a random experiment with distribution B(3.3), that is, three trials and outcome probability. We say that a random variable has distribution B(n,p). The binomial distribution Finding probabilities of successesĪ binomial distribution has two parameters: n, the number of trials, and p, the probability of the outcome of interest ("success"). It will hopefully be expanded in the future.Īll distributions will be used with the "display" command, but of course they may likewise be used in programming etc. Multiple Imputation: Analysis and Pooling Stepsįunctions: Statistical (or Probability) DistributionsĪs the title indicates, presently this section deals with statistical functions only, and a small selection at that.Confidence Intervals with ci and centile.Changing the Look of Lines, Symbols etc.
