ScienceSuit has a number of built-in functions for both discrete and continuous probability distributions and for each of these distributions, similar to R, ScienceSuit has four primary functions. Each function has a one letter prefix (d, p, q, r) followed by the root name of the distribution. For example, dnorm is the height of the density of a normal distribution whereas dbinom returns the probability of an outcome of a binomial distribution.
The following tables can prove to be handy to understand the meaning of the prefixes and also relating distributions to the function names. (From statistics notes of Bret Larget, 2003):
|d||density||probability (probability mass function)|
|p||probability||probability (cumulative distribution function)|
