The kth percentile or quantile, Pk, is a value such that k % of the values are less than Pk and (100 – k)% are greater in value. For example the 90th percentile is a value such that 90% of the observations are smaller than P90 and 10% are greater.

A quantile times 100 is the percentile, so x(1) is also the (1/n) x 100 th percentile of the data. With this convention, however, the largest observation becomes the 100 percentile of the data, which presents a problem as the 100 percentile of a normal distribution is infinity, the …

Also important for environmental data are the 90th, 95th, and 99th percentile where an analyst would like to be sure that 90%, 95%, or 99% of the contamination levels are below a fixed risk level. Quantiles: A quantile is similar in concept to a percentile; however, a percentile represents a percentage whereas a quantile represents a fraction.

Quantile (q) These functions provide the desired quantile (percentile/100) of the specified distribution. The first argument is the value of probability between 0 and 1; the other arguments specify the parameters of the distribution. Random sample (r) These functions generate a vector of random sample from the specified distribution.
