alpha一般唯一的,但是功效不总是唯一的 H1是简单假设时唯一 H1是复合假设时每一个概率函数都会有不同的1-beta值,此时功效取决于多个不同可能的概率函数 由此可以得到功效函数(power function) alpha是一型错误概率 beta是二型错误概率 alpha和1-beta说的都是拒绝零假设 拒绝域如何选取: 一般,alpha减小beta会增加,...
Statistics of neutrinos and the double beta decay We assume that the Pauli exclusion principle is violated for neutrinos, and thus, neutrinos obey at least partly the Bose–Einstein statistics. The paramet... AS Barabash,AD Dolgov,R Dvornický,... - 《Nuclear Physics B》 被引量: 38发表:...
Alpha:There are several symbols that we use in statistics. Some of these are the symbols alpha (α) and beta (β). Each of these symbols has its own corresponding meaning.Answer and Explanation: Become a Study.com member to unlock this answer! Create your account View this answer ...
The proliferation of smart beta strategies has raised questions about the relationship between the core riskfactorsthat have formed the foundation of quantitative investment analysis for decades and the growingfactor zooof strategies. Whereas some state that “smart beta is the vehicle to deliver factor...

These frequencies represent the predominant frequency bands of EEG (i.e. delta, theta, lower alpha, upper alpha, beta, and gamma). Wavelet power was computed by taking the variance of the complex valued wavelet coefficients across trials, then computing their absolute value. This returns the ...
Vertebrate skin appendages are constructed of keratins produced by multigene families. Alpha (α) keratins are found in all vertebrates, while beta (β) keratins are found exclusively in reptiles and birds. We have studied the molecular evolution of thes

Protein aggregation and abnormal lipid homeostasis are both implicated in neurodegeneration through unknown mechanisms. Here we demonstrate that aggregate-membrane interaction is critical to induce a form of cell death called ferroptosis. Importantly, th
