We consider estimation and inference for a regression coefficient in panels with interactive fixed effects (i.e., with a factor structure). We show that previously developed estimators and confidence intervals (CIs) might be heavily biased and size-distorted when some of the factors are weak. We...

Food products are a critical part of everyday life. These products have different types, like perishable, livestock, etc. To increase the efficiency of the food supply chain, designing a comprehensive mathematical model that considers all crucial aspects of the chain is necessary. Therefore,...

The present study initiates the use of repetitive sampling (RS) for CUSUM type statistics discussed by Riaz et al. (2017) and couples it with the Shewhart chart (termed as RS-SEC-TCC) by targeting two objectives, i.e. robustness to non-normality and detection of small to large mean shifts...

Edge computing brings computing and storage resources close to end-users to support new applications and services that require low network latency. Examples of such applications include augmented reality, connected cars, gaming and video analytics. The latency of accessing such applications must...
