The cumulative sum (CUSUM) control chart is widely used in industry for the detection of small and moderate shifts in process location and dispersion. For efficient monitoring of process variability, we present several CUSUM control charts for monitoring changes in standard deviation of a normal process. The newly developed control charts based on well-structured sampling techniques - extreme r...

Attribute sampling is a powerful quality inspection tool. The Lot Acceptance Sampling Plans (LASPs) for sampling by attributes represent a valuable method of quality inspection. Significant LASPs such as the c=0, Dodge-Romig, Philips as well as ANSI/ASQC Z1.4 which replaced MIL-STD 105E have comprehensive procedures and statistical base. A single LASP can be implemented efficiently if inspectio...

This paper has been published in the Journal of Statistical Software (Kiermeier 2008) and describes the framework for creating and visualising acceptance sampling plans. Manufacturers and government agencies frequently use acceptance sampling to decide whether a lot from a supplier or exporting country should be accepted or rejected. International standards on acceptance sampling provide sampli...

A large health survey was combined with a simulation study to contrast the reduction in bias achieved by double sampling versus two weighting methods based on propensity scores. The survey used a census of one New York county and double sampling in six others. Propensity scores were modeled as a logistic function of demographic variables and were used in conjunction with a random uniform variat...

In 2007, there were 33.2 million people around the world living with HIV/AIDS (UNAIDS/WHO, 2007). In May 2003, the U.S. President announced a global program, known as the President's Emergency Plan for AIDS Relief (PEPFAR), to address this epidemic. We seek to estimate patient mortality in PEPFAR in an effort to monitor and evaluate this program. This effort, however, is hampered by loss to fol...

We present a Bayesian sampling approach to parameter estimation in a discrete– response model with double rules of selectivity, where the dependent variables contain two layers of binary choices and one ordered response. Our investigation is motivated by an empirical study using such a double–selection rule for three labor–market outcomes, namely labor force participation, employment and occupa...

We propose a new procedure to detect jumps in prices in the presence of microstructure noise. The procedure averages the results from existing tests across sampling frequencies. This approach overcomes the sub-sampling and low-power problems that plague existing tests for jumps. We use a modified version of Fisher’s method to combine p-values for the Barndorff-Nielsen and Shephard (2006) test a...

PURPOSE/OBJECTIVES To measure differences in cyclosporine A (CSA) trough concentrations from blood collected as a peripheral sample and from a CSA-uncontaminated (naive) lumen of a double-lumen central line. DESIGN Prospective, comparative study. SETTING Pediatric university teaching hospital in metropolitan Australia. SAMPLE 71 paired central and peripheral CSA blood samples from a conve...

In two-phase sampling, the second-phase sample is often a stratified sample based on the information observed in the first-phase sample. For the total of a population characteristic, either the double-expansion estimator or the reweighted expansion estimator can be used. Given a consistent first-phase replication variance estimator, we propose a consistent variance estimator that is applicable ...

We have developed a 1/1.7-inch 20Mpixel back-illuminated stacked CMOS image sensor with parallel multiple sampling plus the two simultaneous output streams. This sensor has achieved the RMS random noise of 1.3ewith the parallel multiple sampling and the two simultaneous output streams of 4Mpixel for a movie mode and 16Mpixel for a still mode with a 2.3Gb/s/lane high-speed interface. The stacked...
