%description
Sequential Monte Carlo (SMC) algorithms for fitting a generalised additive
mixed model (GAMM) to surface-enhanced resonance Raman spectroscopy
(SERRS), using the method of Moores et al. (2016) <arXiv:1604.07299>.
Multivariate observations of SERRS are highly collinear and lend
themselves to a reduced-rank representation. The GAMM separates the SERRS
signal into three components: a sequence of Lorentzian, Gaussian, or
pseudo-Voigt peaks; a smoothly-varying baseline; and additive white noise.
The parameters of each component of the model are estimated iteratively
using SMC. The posterior distributions of the parameters given the
observed spectra are represented as a population of weighted particles.
