Description: Two models are presented for the response times of different operators to different tasks      where response is initiated by one or more cues provided by the system. One model for      the log-response times is a mixed or latent factor model with unequal case fixed effects      and variances. The other model for the log-response times is a non-Gaussian      log-extreme-value model. Procedures for estimating the parameters by maximum      likelihood are presented. The models are used to analyze response time data from      simulator experiments involving nuclear power plant operators performing certain      safety-related tasks. The findings of the models are critiqued and applications to risk      analysis are sketched. Keyword: Extreme-value distribution; Weibull distribution. (KR)
