Abstract Details

2018, Master of Arts, Ohio State University, Psychology.
Houpt et al. (2016) developed a semiparametric Bayesian model to estimate the hazard distributions of response time data. In this thesis, I update the semiparametric model with a more flexible structure which fits better to RT data with respect to MSE and WAIC criteria. I apply the updated model to published data sets (Schwarz, 2001; Palmer et al., 2011) to evaluate the plausibility of some commonly used parametric RT distribution proposals, including ex-Gaussian, Weibull, Gamma, Log-normal, Wald and ex-Wald distributions. Results show a considerable amount of inconsistency between the estimated hazard distributions from the semiparametric Bayesian model and parametric models, indicating that these parametric distribution proposals may not be flexible enough to characterize the traits of RT data. I also use the updated model to obtain a detailed hazard distribution estimation of RT data from Lappin et al. (2016), which has proposed a hazard function model but lacks satisfying hazard estimation tools. The updated semiparametric model is able to capture some critical hazard distribution traits which provide evidence to evaluate the underlying hypotheses of Lappin et al. (2016)'s model.
