Abstract: With the third iteration of the no-test UP college admission, there is a need to study, assess, and address if the excellence with economic and geographic equity creed worked. This research looks into the collective characteristics of applicants from Metro Manila and all provinces as they are geospatially distributed, accounting for variation in the information asked in the UPCA application process. Specifically, the research describes the spatial distribution of applicant characteristics at the provincial level; determines if spatial autocorrelation is present among the number of qualifiers and qualifying rates of provinces; and formulates a model that significantly explains variability in the number of qualifiers given spatial autocorrelation and other explanatory variables.

Abstract: This paper proposes to use a spatio-temporal model with structural change for the spread of the coronavirus disease 2019 (COVID-19), showing its suitability in the pandemic experience in the Philippines, from the first recorded case in the country to the end of the fourth surge in October 2021. This model was originally proposed by Bastero and Barrios in 2011. The result uses a spatiotemporal model that incorporates the forward search algorithm and maximum likelihood estimation into the backfitting framework. The forward search algorithm is used to filter the effect of short-term structural change in the estimation of covariate and spatial parameters. The method that uses the effect of structural change offers good model fit especially in COVID-19 experience in the Philippines where structural change is encountered at different space and time. It is further explored in this paper how this spatiotemporal model may be incorporated in the compartmental mathematical models for COVID-19.

Keywords: spatio-temporal model, structural change, forward search, COVID-19

Abstract: Statistical matching deals with methods of combining different data from different sources to get information on variables not observed in a single source. With the goal of estimating a Poisson regression model, this study explores statistical matching techniques and estimation procedures involving bootstrap. Simulation studies confirmed that Poisson regression imputation and MCMC imputation produce comparable results. It also showed that "bootstrap within" method performs well regardless of the matching method used.

Keywords:
statistical matching, count data, imputation, bootstrap

Abstract: We propose a two-stage latent Gaussian model for a specific spatial misalignment problem. We use the integrated nested Laplace approximation (INLA) to perform inference. The first-stage model is based on the Bayesian melding which does data fusion by assuming a common latent field for the observed outcomes. We use the stochastic partial differential equations (SPDE) approach to efficiently estimate the spatial field. It induces a Markov structure on the field which leads to sparse precision matrices giving great computational gains. Uncertainty in the first stage is accounted for by simulating repeatedly from the posterior predictive distribution of the field. A simulation study was carried out to assess the impact of the sparsity of the data, the number of time points, and the specification of the priors in terms of the biases, RMSEs, and coverage probabilities. The results show that the parameters are generally estimated correctly, but there is difficulty in estimating the random field parameters. The method is applied to NO2 concentration and respiratory hospitalizations for the year 2017 in England. An increase in NO2 levels is significantly associated with an increase in the relative risks of the health outcome. Also, there is a strong spatial structure and a strong temporal autocorrelation in the risks.

Abstract: The talk discusses a roadmap to achieving financial freedom - its stages and the Philippine experience. Sources and expected amounts of retirement funds from mandated social insurance and private employers will be covered. Building an individual retirement account as early as possible will be highlighted to supplement these retirement benefits provided by law. A worksheet will be provided to participants to enable them to determine the amount they need to retire comfortably at the age they desire to retire.

Abstract: We will discuss the basic elements of clinical trials and the role of biostatistics in these trials. Two specific trials will serve as illustrations. First trial is the completed MGTX Trial, a randomized blinded controlled study of a surgical treatment for myasthenia gravis. The second trial is the ongoing TeleCOPD, a randomized controlled trial that tests whether a video telehealth pulmonary rehabilitation intervention for COPD patients will reduce hospital readmissions, improve quality of life, and be cost-effective. I will summarize the skills and knowledge to be a successful biostatistician in clinical trial research. I will end the talk with a brief discussion of the Biostatistics graduate programs and certificates offered at UAB.
