init_abscissa: Initialize Abscissas

In vdchoi/ars: Adaptive Rejection Sampler

Description

Initialize the abscissas (x vector), based on the function domain D. If D is bounded, select xs with equal distances, excluding the bounds If D is left/right unbounded, select first/last x based on h's derivative values

Usage

init_abscissa(h, a, b, init_k = 20)

Arguments

h	log density function
a	lower bound of function domain D (could be -Inf)
b	upper bound of function domain D (could be Inf)
init_k	number of xs in the initial abscissa, default is 20

Value

a vector consisting of all xs in the abscissa
