Starting from the Beta (2, 2) model, connected to the Verhulst logistic parabola, several
extensions are discussed, and connections to extremal models are revealed. Aside from the …

The BetaBoop (p, q, P, Q), p, q, P, Q> 0, family of random variables includes as special
cases Beta (p, q) random variables, which are known to be quite versatile in modeling …

Random damage—deletion of (X1: 2, X2: 2) from [0, 1]—followed by random repair,
meaning the union of (Y1: 2, Y2: 2) to the damaged set, where X and Y are independent …

No empreendimento coletivo que é a Ciência é frequente ser necessário harmonizar
resultados contraditórios, ou extrair conclusões de experiências independentes que em si …

The Verhults differential equation d dt N (t)= r N (t)(1− N (t)) and its logistic parabola
difference equation counterpart xt+ 1= αxt (1− xt) I (0, 1)(xt), α∈[0, 4], are tied to sustainable …
