Research ArticleOpen accessIn the keywordsCorrelation Between Dispersion and Mean Toassess Healthcare Servicee FficiencyRamalingam ShanmugamMotivation for this research work started while helping a hospital administrator to assess whether patient oriented activity duration, X≥0 is reflecting the service’s efficiency? Higher value of the sample mean duration, X implies lesser productivity in the hospital and more healthcare cost. Likewise, larger value of sample dispersion, sx2 in the service durations is an indicator of lesser reliability and … …Current Research in Biostatistics, Vol. 2, Issue 2 · 30 Aug 2012 · 6,873 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDoes Over or Under Dispersion in Inverse Binomial Data Suggest Anything? A Case in Point is the Waiting Time for Both Heart-Lung TransplantsRamalingam ShanmugamThe model is an abstraction of the reality. The selection of the usual inverse binomial as an underlying model for the number of patients waiting in months for heart and lung transplant is questionable because the data exhibit not the required balance between the dispersion and its functional equivalent in terms of the mean but rather an over or under … …Current Research in Biostatistics, Vol. 3, Issue 2 · 29 Jan 2014 · 6,888 accessesView PDF Cite

Research ArticleOpen accessIn the abstractImpact of Emissions from Power Stations on the Ambient Air Quality of Selected Urban Areas in KuwaitBader N. Al-Azmi, V. Nassehi, A.R.

Research ArticleOpen accessAll words, across the recordIs Poisson Dispersion Diluted or Over-Saturated? An Index is Created to AnswerRamalingam ShanmugamA prelude to interpret a pattern in the repeating incidences is to identify the underlying frequency distribution of the collected data. A case in point is the Poisson distribution which is often selected for medical count data such as gene mutations, medication error and number of ambulatory pickups in a day. A requirement for the Poisson distribution is that the … …Current Research in Biostatistics, Vol. 2, Issue 2 · 24 May 2013 · 6,614 accessesView PDF Cite
