Distribution of geometrically weighted sum of bernoulli ramdom variables
(Scientific Research, www.scirp.org/, 2011)A new class of distributions over (0,1) is obtained by considering geometrically weighted sum of independent identically distributed (i.i.d.) Bernoulli random variables. An expression for the distribution function (d.f.) is ... -
Ehrenberg law-like relationship and anthropometry
(Wiley-Blackwell, www.wiley.com/wiley-blackwell, 2002)Summary. Ehrenberg presented the simple law-like relationship log(w) = 0.8h + 0.4 ? 0.04 between the weight and height of children aged 5-13 years. Several researchers have confirmed that this relationship holds, irrespective ... -
