full_sc_lhood_fast

Optimized implementation used by estimation workflows.
Intended to be numerically consistent with <code>full_sc_lhood()</code>.

internal

A suite of tools for estimating, assessing model fit, simulating from, and visualizing location dependent marked point processes characterized by regularity in the pattern.
You provide a reference marked point process, a set of raster images containing location specific covariates, and select the estimation algorithm and type of mark model.
'ldmppr' estimates the process and mark models and allows you to check the appropriateness of the model using a variety of diagnostic tools.
Once a satisfactory model fit is obtained, you can simulate from the model and visualize the results.
Documentation for the package 'ldmppr' is available in the form of a vignette.
