In clinical research, parameters required for sample size calculation are usually unknown. A typical approach is to use estimates from some pilot studies as the true parameters in the calculation. This approach, however, does not take into consideration sampling error. Thus, the resulting sample size could be misleading if the sampling error is substantial. As an alternative, we suggest a Bayes...
background: in this study, a method for linear attenuation coefficient calculation was introduced. methods: linear attenuation coefficient was calculated with a new method that base on the physics of interaction of photon with matter, mathematical calculation and x-ray spectrum consideration. the calculation was done for cerrobend as a common radiotherapy modifier and mercury. results: the valu...
The calculation of multipoint likelihoods is computationally challenging with the exact calculation of multipoint probabilities only possible on small pedigrees and many markers or large pedigrees and few markers. This paper explores the utility of approximating multipoint likelihoods using data on markers flanking a hypothesized position of the trait locus. The calculation of such likelihoods ...
