Ascertainment-adjusted parameter estimates revisited.
Ascertainment-adjusted parameter estimates from a genetic analysis are typically assumed to reflect the parameter values in the original population from which the ascertained data were collected. Burton et al. (2000) recently showed that, given unmodeled parameter heterogeneity, the standard ascertainment adjustment leads to biased parameter estimates of the population-based values. This findin...
متن کاملAdjusted Power Estimates
Critical values and powers of competing tests are often evaluated through Monte Carlo simulations. Since the true levels of those tests are often very diierent, comparisons of the power estimates are not valid. We suggest that Monte Carlo estimates of critical values be used to create adjusted power estimates which are then comparable. The main contribution is to analyze the variability of the ...
متن کاملThe Telicity Parameter Revisited
The goals of this paper are threefold: First, to review some recent syntactic accounts of cross-linguistic differences in the expression of telicity in Slavic vs. Germanic languages. Second, I will argue that the parametric variation in the encoding of telicity cannot be based on a unidirectional specifier head agreement between the verbal functional head linked to the telicity of the VP and th...
متن کاملAdjusted estimates for time-to-event endpoints.
In the analysis of retrospective data or when interpreting results from a single-arm phase II clinical trial relative to historical data, it is often of interest to show plots summarizing time-to-event outcomes comparing treatment groups. If the groups being compared are imbalanced with respect to factors known to influence outcome, these plots can be misleading and seemingly incompatible with ...
متن کاملEstimation of parameter of proportion in Binomial Distribution Using Adjusted Prior Distribution
Historically, various methods were suggested for the estimation of Bernoulli and Binomial distributions parameter. One of the suggested methods is the Bayesian method, which is based on employing prior distribution. Their sound selection on parameter space play a crucial role in reducing posterior Bayesian estimator error. At times, large scale of the parametric changes on parameter space bring...
