Probability Distributions

In Chapter 6, you will learn how to use R for several important probability distributions. We cover the binomial distribution, the Poisson distribution, the normal distribution, the t distribution, the F distribution, and the chi-square distribution. R uses a standardized method for naming the functions associated with each of these, so that it is easy to remember them. We use the letters d (for density), p (for probability), q (for quantile), and r (for random) to preface the function, so for the normal distribution, dnorm returns the density, pnorm returns the probability associated with an area under the ...
