Given the increasing volume of data available, much of which lacks established categories, the development of algorithms capable of finding patterns in raw, unclassified data is becoming increasingly important. One type of clustering algori...
A review and comparison of methods of testing for heteroskedasticity in the linear regression model [0.03%]
线性回归模型中异方差性检验方法的述评与比较

Thomas Farrar et al.
This study reviews inferential methods for diagnosing heteroskedasticity in the linear regression model, classifying the methods into four types: deflator tests, auxiliary design tests, omnibus tests, and portmanteau tests. A Monte Carlo si...
Inconsistency of three indices in measuring the association between the risk factor and the risk of a disease [0.03%]

Here we consider a weighted version of the negative binomial distribution and illustrate its usefulness through fitting Covid-19 datasets. We obtain several important properties of the distribution such as probability generating function, c...
Generalised random tessellation stratified sampling over auxiliary spaces [0.03%]
基于辅助空间的广义随机镶嵌分层抽样方法

B L Robertson et al.
Generalised Random Tessellation Stratified (GRTS) is a popular spatially balanced sampling design. GRTS can draw spatially balanced probability samples in two dimensions but has not been used to sample higher-dimensional auxiliary spaces. T...
Lasso Monte Carlo, a variation on multi fidelity methods for high-dimensional uncertainty quantification [0.03%]
