Background Cigarette sharing has not been assessed at the provincial level or analysed the degree of its association with smoking cessation in China. Such analysis would provide critical intelligence ...

Systematic sampling is straightforward and low risk, offering better control. However, it may introduce sampling errors and ...

This example illustrates the use of regression analysis in a simple random cluster sampling design. The data are from S rndal, Swenson, and Wretman (1992, p. 652). A total of 284 Swedish ...

These versatile strategies—from brain dumps to speed sharing—help students track their own progress while informing your next instructional steps.

Stratified random sampling - random samples are taken from within certain categories. Stratified systematic sampling - regular samples are taken from within certain categories.

Abstract: Spatial resolution is a critical factor in promoting the deployment of Light Detection And Ranging (LiDAR). In our point-scanning single-photon avalanche diode (SPAD) LiDAR at NYCU, the ...

A machine learning model incorporating functional assessments predicts one-year mortality in older patients with HF and improves risk stratification beyond established scores. Functional status at ...

Abstract: A physical random code (PRC) multiple-input multiple-output (MIMO) radar system is proposed and experimentally demonstrated for three-dimensional (3D) multi-target imaging. The radar system ...

This systematic review and meta-analysis identified prognostic factors associated with early mortality in septic shock. The identification of these prognostic factors could aid in clinical risk ...
