Statistical methods for evaluating dose-response relationship

Statistical challenges in evaluating dose-response using epidemiological data.

Statistical Tests for Evaluating Earthquake Prediction Methods

The impact of including postcursors in the null hypothesis test is discussed. Unequal prediction probabilities can be included in the null hypothesis test using a generalization of the central limit theorem. A test for determining the enhancement factor over random chance is given. The seismic earthquake signal may preferentially precede earthquakes even if the VAN methodology fails to forecast...

Dose-response relationship of phototherapy for hyperbilirubinemia.

BACKGROUND AND OBJECTIVE Using light-emitting diodes during conventional phototherapy, it is possible to reduce the distance from light source to infant, thus increasing light irradiance. The objective of this study was to search for a "saturation point" (ie, an irradiation level above which there is no further decrease in total serum bilirubin [TsB]). This was a prospective randomized study pe...

Dose-response relationship for breast cancer induction at radiotherapy dose

PURPOSE Cancer induction after radiation therapy is known as a severe side effect. It is therefore of interest to predict the probability of second cancer appearance for the patient to be treated including breast cancer. MATERIALS AND METHODS In this work a dose-response relationship for breast cancer is derived based on(i) the analysis of breast cancer induction after Hodgkin's disease,(ii) ...

islanding detection methods for microgrids

امروزه استفاده از منابع انرژی پراکنده کاربرد وسیعی یافته است . اگر چه این منابع بسیاری از مشکلات شبکه را حل می کنند اما زیاد شدن آنها مسائل فراوانی برای سیستم قدرت به همراه دارد . استفاده از میکروشبکه راه حلی است که علاوه بر استفاده از مزایای منابع انرژی پراکنده برخی از مشکلات ایجاد شده توسط آنها را نیز منتفی می کند . همچنین میکروشبکه ها کیفیت برق و قابلیت اطمینان تامین انرژی مشترکان را افزایش ...
