Create an exponential distribution

create_exp_distr(id = NA, mean = 1, value = NA, lower = NA, upper = NA)

Arguments

id

the distribution's ID

mean

the mean parameter, a numeric value. For advanced usage, use the structure as returned by create_mean_param

value

the initial value for the MCMC

lower

the lower bound, the lowest possible value

upper

an upper limit of the uniform distribution. If the upper limits needs to be infinity, set upper to Inf.

Value

an exponential distribution

  beast2_input_file,
  tree_prior = create_yule_tree_prior(
    birth_rate_distr = exp_distr
  )
)
file.remove(beast2_input_file)
#> [1] TRUE
