estimate: estimate

In Michorlab/estipop: ESTIpop is a simulation software tool written in C++ to simulate and estimate rate parameters for general multitype branching processes

Description

Estimates the rate parameters for a general multitype branching process with constant rates

Usage

estimate(model, init_pop, times, final_pop, initial_params, lower = NULL,
  upper = NULL, trace = 1)

Arguments

model	the process_model object representing the process generating the data
init_pop	a nobs x ntype matrix with initial population for each observation
final_pop	the nobs x mtype matrix of final populations observed
initial_params	vector of initial parameters estimates for MLE optimization
lower	vector of lower bounds on rate parameters for optimization
upper	vector of upper bounds on rate parameters for optimization
trace	level of output for optimizer - see optim function, control - trace for "L-BFGS-B" method
params	the vector of parameters for which we are computing the likelihood
time	the nobs length vector containing the time between the initial and final population observations
