A Critical Review of Statistical Methods Used in Quality Control
Sans, Wolfgang - In: Stochastics and Quality Control 27 (2013) 2, pp. 97-142
Abstract. Industrial quality control is one of the most important activities in modern production systems. Each undetected quality flaw may have disastrous consequence not only for the functioning of products, but also from the view point of safety and financial losses. The methods used in...

Branching Process Modelling of COVID-19 Pandemic Including Immunity and Vaccination
Atanasov, Dimitar; Stoimenova, Vessela; Yanev, Nikolay M. - In: Stochastics and Quality Control 36 (2022) 2, pp. 157-164
Abstract We propose modeling COVID-19 infection dynamics using a class of two-type branching processes. These models require only observations on daily statistics to estimate the average number of secondary infections caused by a host and to predict the mean number of the non-observed infected...

Blood, Sweat, and Tears: The Rise and Decline of the East German Economy, 1949–1988 / Blut, Schweiß, Tränen: Aufstieg und Niedergang der ostdeutschen Wirtschaft, 1949–1988
Blum, Ulrich; Dudley, Leonard - In: Jahrbücher für Nationalökonomie und Statistik 220 (2000) 4, pp. 438-452
Summary The rise of the East-German economy in the 1950s and 1960s and its decline in the 1970s and 1980s is difficult to explain by neoclassical economics. However; the observed life cycle may be explained by the inclusion of concepts from old and new institutional economics and from functional...

Optimal choice of k n -records in the extreme value index estimation
El Arrouchi, Mohamed; Imlahi, Abdelouahid - In: Statistics & Decisions 23 (2005) 2, pp. 101-115
Summary We propose an estimate for the index of extreme value distribution which based on k n -record values and show its consistency and asymptotic normality. The problem of specifying the optimal value of k  =  k n involved in our estimator is investigated. Some simulation results are also...
