`dot-quantities.Rd`

Formulas for quantities (such as mean, variance, skewness, EVI, etc.) of select parametric distributions.

`.quantities`

An object of class `list`

of length 18.

A list, where each distribution gets a (named) entry, with name
given by the suffix of `dst_`

(such as "norm", "unif", etc.). Each
distribution's entry is itself a named list of expressions, where the
name is the name of the quantity matching the distionary function name:

mean

median

variance

skewness

kurtosis_exc

range

evi

Each expression is allowed to refer to the distribution's parameters by name.

Although R allows us to evaluate distributional representations
of certain parametric distributions through functions with
`p`

, `d`

, `q`

, and `r`

prefixes (such as `pnorm()`

, `dnorm()`

, etc.),
R does not "come with" formulas for quantities such as mean, variance,
EVI, etc. Although these quantities can be computed from a distributional
representation (such as integrating the quantile function to get the mean),
it's often inefficient to rely on such computations. We therefore include
formulas here, and check them using testthat.
