Web8.1 R as a set of statistical tables. One convenient use of R is to provide a comprehensive set of statistical tables. Functions are provided to evaluate the cumulative distribution function P(X <= x), the probability density function and the quantile function (given q, the smallest x such that P(X <= x) > q), and to simulate from the distribution. Web14.6 - Uniform Distributions. Uniform Distribution. A continuous random variable X has a uniform distribution, denoted U ( a, b), if its probability density function is: f ( x) = 1 b − a. for two constants a and b, such that a < x < b. A graph of the p.d.f. looks like this: f (x) 1 b-a X a b. Note that the length of the base of the rectangle ...
