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. WebProbability distribution definition and tables. In probability and statistics distribution is a characteristic of a random variable, describes the probability of the random variable in each value. Each distribution has a certain probability density function and probability distribution function.
