Motivation 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 t...

Confidence Intervals for Signal to Noise Ratio of a Poisson Distribution

Florence George — 2012-09-19

Current Research in Biostatistics, Published online: 19 September 2012; doi:10.3844/amjbsp.2011.44.55

The Poisson distribution is one of the most useful probability distributions to fit rare event data. Confidence interval for the SNR is an important issue among the researchers in image processing. Th...

Is Poisson Dispersion Diluted or Over-Saturated? An Index is Created to Answer

Ramalingam Shanmugam — 2013-05-24

Current Research in Biostatistics, Published online: 24 May 2013; doi:10.3844/amjbsp.2011.56.60

A 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 sele...
