sd function

Returns the standard deviation of one or more delay distribution

This works out the standard deviation of all the (parametric / nonparametric) delay distributions combined in the passed <dist_spec>. If any of the parameters are themselves uncertain then NA is returned.

## S3 method for class 'dist_spec'
sd(x, ...)

Arguments

• x: The <dist_spec> to use

Returns

A vector of standard deviations.

Examples

## Not run:

# A fixed lognormal distribution with sd 5 and sd 1.
dist1 <- LogNormal(mean = 5, sd = 1, max = 20)
sd(dist1)

# A gamma distribution with mean 3 and sd 2
dist2 <- Gamma(mean = 3, sd = 2)
sd(dist2)

# The sd of the sum of two distributions
sd(dist1 + dist2)
## End(Not run)
