Based on a quantitative meta-analysis of empirical studies, this article points out a significant flaw in the Three Worlds of Welfare literature, the "variable selection problem." Compiling, classifying, and qu
本文研究了基于面板数据的分位数回归模型的变量选择问题.通过增加改进的自适应Lasso惩罚项,同时实现了固定效应面板数据的分位数回归和变量选择,得到了模型中参数的选择相合性和渐近正态性.随机模拟验证了该方法的有效性.推广了文献[14]的结论.In this paper, we consider the variable selection problem for the quan...

In particular, the literature on welfare state change and retrenchment has not only introduced new conceptual perspectives, but also trig- gered a methodological debate about the selection of suitable measurements of social policy-making—the so-called dependent variable problem (e.g. Clasen & Siegel...
{G}=0\), Eq.10reduces to a least squares minimization problem. As a side note, before performing the regularized SCA analysis, all columns inXkmay be mean-centered and scaled to norm one or to\({J}_{k}^{-\mathrm{1/2}}\)in order to give all blocks - even those that contain ...
Leveraging recent results in the variable selection literature, we show that an estimator based on spike and slab priors achieves optimal localization rate in the multiple offline change point detection problem. Based on this estimator, we propose a Bayesian change point detection method, which is ...
I have a problem with a variable. I created new variable for 0CALMONTH. The business case is: I have to show current month that I choose on the selection screen and the previous month. I used the standard option in BEx designer when you decrease the received value by -1. When i st...

In the second problem, NIR spectrometry is employed to discriminate diesel samples with respect to the concentration level of sulphur. This application illustrates the use of SPA-LDA in a large-scale variable selection scenario. In these two examples, SPA-LDA is compared with the commonly used ...
Smart Selection lets you select single words / characters you've written using your pencil using iOS text recognition features DataDetectors are used to automatically detect e.g. phone numbers, email addresses AirPods are now able to automatically switch to new incoming audio sources Spatial Audio...
