Estimation of a Two-component Mixture Model with Applications to Multiple Testing [PDF]
We consider a two-component mixture model with one known component. We develop methods for estimating the mixing proportion and the unknown distribution nonparametrically, given i.i.d.~data from the mixture model, using ideas from shape restricted ...

ABSTRACT Objectives To identify predictors of chronic ITP (cITP) and to develop a model based on several machine learning (ML) methods to estimate the individual risk of chronicity at the timepoint of diagnosis. Methods We analyzed a longitudinal cohort of 944 children enrolled in the Intercontinental Cooperative immune thrombocytopenia (ITP) Study ...

Estimation of inertia demand in power systems considering wind power virtual inertia
The high proportion of renewable energy integrated into the grid through numerous power electronic devices has reduced the overall system inertia level and operational stability and caused poor disturbance resistance.

Exact Methods for Multistage Estimation of a Binomial Proportion [PDF]
We first review existing sequential methods for estimating a binomial proportion. Afterward, we propose a new family of group sequential sampling schemes for estimating a binomial proportion with prescribed margin of error and confidence level.

Estimating the Null and the Proportion of non-Null effects in Large-scale Multiple Comparisons [PDF]
An important issue raised by Efron in the context of large-scale multiple comparisons is that in many applications the usual assumption that the null distribution is known is incorrect, and seemingly negligible differences in the null may result in large

ABSTRACT Surveillance imaging aims to detect tumour relapse before symptoms develop, but it's unclear whether earlier detection of relapse leads to better outcomes in children and young people (CYP) with medulloblastoma and ependymoma. This systematic review aims to identify relevant literature to determine the efficacy of surveillance magnetic ...

Parameter Estimation of ZZ Distribution under Progressive Type-II Censored Data
ZZ distribution is suitable to describe the life variable of a type of storage products that rarely fail before a given design life,and the proportion of failures has increased significantly after the design life.

Classification with Asymmetric Label Noise: Consistency and Maximal Denoising
In many real-world classification problems, the labels of training examples are randomly corrupted. Most previous theoretical work on classification with label noise assumes that the two classes are separable, that the label noise is independent of the ...
