sed_rate_gen_from_bounds {admtools} | R Documentation |
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)

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
