Cystic Fibrosis (CF) is an inherited disease that affects multiple organ systems. It is the most common cause of severe progressive lung disease and exocrine panceratic insufficiency. In our investigation 67 patients had CF. Of these, 79% had panceratic insufficiency and 92% had lung disease under 2 years age. Also 67% of patients were < 2 percentile and 28% between 3-10 percentile weight for a...
Although the percentile-based control charts are very effective with guaranteed in-control and out-of-control run lengths in statistical process control, they still lack algorithmic (especially) software support. The proposed (pbcc) tool fills this gap. This is freely available implements recent work on individual as well joint charts.
This paper considers the problem of estimating the population mean Ybar of the study variate Y using information on different parameters such as population mean $(bar{X})$, coefficient of variation $(C_x)$, kurtosis $beta_{2(x)}$, standard deviation $(S_x)$ of the auxiliary variate x and on the correlation coefficient, $rho$, between the study variate $Y$ and the auxiliary variate $...
In this paper, a new control chart to monitor multi-binomial processes is first proposed based on a transformation method. Then, the maximum likelihood estimators of change points designed for both step changes and linear-trend disturbances are derived. At the end, the performances of the proposed change-point estimators are evaluated and are compared using some Monte Carlo simulation experimen...
OBJECTIVE To examine the association of BMI percentile and change in BMI percentile to change in blood pressure (BP) percentile and development of hypertension (HTN). METHODS This retrospective cohort included 101 606 subjects age 3 to 17 years from 3 health systems across the United States. Height, weight, and BPs were extracted from electronic health records, and BMI and BP percentiles were...
