EWMA control chartoutlierFHRtruncated normal distributionIn many applications, it is very important to detect outliers during the analysis of normal data. Many existing methods preprocess the data to remove the outliers and then analyse the data accordingly when the data are contaminated by different ...
Figure 1 shows a chart of the log-normal distribution with mean 0 and standard deviations 1, .5 and .25. Figure 1 – Chart of Log-normal Distribution Note that the log-normal distribution is not symmetric, but is skewed to the right. If you have data that is skewed to the right that...
Metformin is a widely-used treatment for type 2 diabetes and is reported to extend health and lifespan as a caloric restriction (CR) mimetic. Although the benefits of metformin are well documented, the impact of this compound on the function and organiza
np Control ChartAcceleration FactorIn this manuscript, a new hybrid exponentially weighted moving average chart using the exponential distribution is given. The complete structure of the proposed control chart is given. A Monte Carlo simulation is given for the proposed control chart. The necessary ...
This problem can be solved by fitting a suitable model to the data and using the control chart for the residuals. The problem becomes very important, when the distribution of observation is nonnormal, in addition to being autocorrelated. Much recent research has focused on the development of ...
In this article, we design an extended exponentially weighted moving average (EEWMA) chart under the assumption of inverse Maxwell (IM) distribution, an IM EEWMA (IMEEWMA) control chart. We have estimated the performance of the proposed chart in terms of various run-length (RL)...
Lognormal distribution has been widely used in engineering related issues. In this manuscript, attribute control chart is designed for lognormal distribution under the time-censoring conditions. The control chart coefficient is determined for which false signals are minimized. The average run length (...

A Markov chain procedure is applied to evaluate the statistical performance of the chart by using ...

However, this chart requires to know (or to be able to estimate from historical data) at least the in-control covariance matrix. Unfortunately, even if very small images, e.g., \\(100imes 100\\) pixels are vectorized, the covariance matrix is of the size \\(10^4imes 10^4\\) and...
