Hi Richard, Tirthankar
I might also suggest:
Oh, M.-S., & Lim, Y.B. (2001). Bayesian analysis of time series Poisson data. Journal of Applied Statistics, 28(2), 259-271.
Drescher, D. (2008). Testing for presence of a latent process in count series. Journal of Statistical Computation and Simulation, 78(7), 595-607.
Jung, R.C., Kukuk, M., & Liesenfeld, R. (2006). Time series of count data: modeling, estimation and diagnostics. Computational Statistics & Data Analysis, 51(4), 2350-2364.
Jorgensen, B., Lundbye-Christensen, S., Song, P.X-K., & Sun, Li. (1999). A State Space Model for Multivariate Longitudinal Count Data. Biometrika, 86(1), 169-181.
Knape, J., Jonzén, N., Sköld, M., & Sokolov, L. (2009). Multivariate state-space modelling of bird migration count data. Environmental and Ecological Statistics, 3(Section I), 59-79.
Knape et al. (2009) model a 54-year time series of various bird species counts, your student might follow their Bayesian strategy... I was also thinking that it might be possible to fit a latent growth curve or multilevel model to this type of data, with Poisson links on the 45 indicators:
Liu, H. (2007). Growth Curve Models for Zero-Inflated Count Data: An Application to Smoking Behavior. Structural Equation Modeling, 14(2), 247-279.
Alosh, M. (2009). Modeling longitudinal count data with dropouts. Pharmaceutical Statistics, 9(1), 35-45.
Min, Y., & Agresti, A. (2005). Random effect models for repeated measures of zero-inflated count data. Statistical Modelling, 5(1), 1-19. Coelho-Barrosa, E.A., Achcar, J.A., & Mazucheli, J. (2010). Longitudinal Poisson modeling: an application for CD4 counting in HIV-infected patients. Journal of Applied Statistics, 37(5), 865-880.
My two cents,
