We propose inference procedures for general factorial designs with time-to-event endpoints. Similar to additive Aalen models, null hypotheses are formulated in terms of cumulative hazards. Deviations are measured in terms of quadratic forms in Nelson

Integration of image processing in order to detect red blood cells (RBCs) in human urine enables technology to reduce medical technician’s manual counting time and error factor. The general objective of this study was to detect and count the red bl

The weight of water contained in paddy rice which is expressed in percent is called Moisture Content. Moisture Content measurement is important to achieve the levels for safe and long-term storage. Accurate measurement also an influence on the market

Much effort has been done to control the “false discovery rate” (FDR) when $m$ hypotheses are tested simultaneously. The FDR is the expectation of the “false discovery proportion” $\text{FDP}=V/R$ given by the ratio of the number of false rej

We address the testing problem of proportional hazards in the two-sample survival setting allowing right censoring, i.e., we check whether the famous Cox model is underlying. Although there are many test proposals for this problem, only a few papers

In the present paper we derive lower asymptotic information bounds of Cramer-Rao type for estimators of nonparametric statistical functionals. The results are based on dense differentiability and dense regularity concepts which lead to weak assumptio

We study the signal detection problem in high dimensional noise data (possibly) containing rare and weak signals. Log-likelihood ratio (LLR) tests depend on unknown parameters, but they are needed to judge the quality of detection tests since they de

Much effort has been made to improve the famous step up test of Benjamini and Hochberg given by linear critical values $\frac{i\alpha}{n}$. It is pointed out by Gavrilov, Benjamini and Sarkar that step down multiple tests based on the critical values

In biomedical research, weighted logrank tests are frequently applied to compare two samples of randomly right censored survival times. We address the question how to combine a number of weighted logrank statistics to achieve good power of the corres
