logFFT: Calculate log-likelihood using generating function technique

In jasonxu90/bdsem: Analysis of discretely observed Birth-Death-Shift processes

Description

logFFT calculates the log-likelihood where transition probabilities are computed using our FFT generating function method

Usage

  logFFT(param, u, simData, initList, s1.seq, s2.seq)

Arguments

param	A vector of three numbers containing the birth, shift, and death rate respectively
u	A number, the observation interval length
simData	An matrix in the format of a list entry returned by makedata.simple
initList	A vector of possible initial populations
s1.seq	A vector of complex arguments evenly spaced along the unit circle
s2.seq	A vector of complex arguments evenly spaced along the unit circle

Value

The negative log-likelihood value
