O procedurze kart kontrolnych w przypadku, gdy zmienna diagnostyczna ma rozkład asymetryczny
(Oficyna Wydawnicza AFM, 2013) Wywiał, Janusz
The problem of statistical quality control is taken into account. A new proposition of control card construction is proposed. The problem is considered as testing statistical hypothesis on expected value of the variable understudy (diagnostic variable) under the assumption that the variable has skewed probability. The proposed test statisticis constructed on the rather well known following property that the covariance between sample variance and sample mean is proportional to the third central moment of a variable. This property is applied to construction of test statistic based on the regression estimator. The limit distribution of the test statistic is normal.
