It is well known that the F distribution function can be expressed as an incomplete beta function. In particular when both degrees of freedom are even, the F distribution function may be simply expressed as a sum of binomial probabilities. In this note we consider the F distribution with at...

At some point in time during a post-surgery period, an anesthesiologist may intervene using a medication to quicken a patient’s conscious-recovery time. An assessment of such intervention methods has clinical importance. One performs an extension of the exponential model to address this issue....

The method of probability-weighted moments is used to derive estimators of parameters and quantiles of the three-parameter Weibull distribution. The properties of these estimators are studied. The results obtained are compared with those obtained by using the method of maximum likelihood. The...

Myelodysplastic syndrome (MDS), sometimes referred to as pre-leukemia or smoldering leukemia, is a group of diseases usually characterized by failure of the bone marrow to produce enough normal blood cells. In about one-third of patients, the disease transforms into acute leukemia. In high-risk...

In some population the AIDS/HIV incidence rate θ∈(0,∞) is altered in the middle of a data collection period due to preventive treatments imposed by the health service agencies. The intervened Poisson (IP) model in [Comput. Programs Biomed. 17 (1983) 89; Biometrics 48 (1985) 559] was...

An empirical investigation based on 222 sports fans of a university basketball team finds that sports enthusiasm and the mere exposure to sponsorship stimuli is positively associated with the awareness of event sponsors. In addition, the findings reveal the negative impact of advertising and...
