Examples

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

# An uncertain gamma distribution with mean 3 and sd 2
gamma <- dist_spec(
 mean = 3, sd = 2, mean_sd = 0.5, sd_sd = 0.5, max = 20,
 distribution = "gamma"
)
mean(gamma)

# The mean of the sum of two distributions
mean(lognormal + gamma)
