sed_rate_gen_from_bounds: seg rate gen from upper/lower bounds

In admtools: Estimate and Manipulate Age-Depth Models

seg rate gen from upper/lower bounds

Description

constructs a sedimentation rate generator for usage with sedrate_to_multiadm based on the following procedure: (1) determine stratigraphic points based on a Poisson point process with rate rate (2) at these points, determine the sedimentation rate based on a uniform distribution between the bounds provided by the input parameters (3) linearly interpolate between those points with sedimentation rate determined in step 2. This approach can be used to estimate age-depth models when only rough boundaries on sedimentation rates are available. Here, the uniform distribution is chosen to reflect that no other information other than maximum and minimum sed. rate is available.

Usage

sed_rate_gen_from_bounds(h_l, s_l, h_u, s_u, rate = 1)

Arguments

h_l	height values for lower bounds
s_l	sed rate values for lower bounds
h_u	height values for upper bounds
s_u	sed rate values for upper bounds
rate	rate of poisson point process

Value

a function factory for usage with sedrate_to_multiadm
