Manipulate the sizes of the leaves with a Weibull distribution

This function returns a function which itself returns a numerical vector of length n_leaves, the number of leaves on the branch. These values serve as relative multiplication factors of the sizes of the leaves of the branch. (The maximum value of this distribution is then normalized to 1.)

Usage

spark_weibull(shape = 1.2, scale_factor = 0.5)

Arguments

shape, scale_factor

Parameters passed to stats::dweibull().

Value

dweibull() function depending on n_leaves as one of the arguments

Examples

#Mark the two consecutive pairs of parentheses:
spark_weibull()(n_leaves = 10)
