Transformada fraccional de Fourier en el caso de un plano imagen inclinado

open access: yesIngeniería y Ciencia, 2010
La conocida fórmula de difracción de Fresnel relaciona la distribución de amplitud compleja de una onda en el plano objeto (campo ondulatorio de entrada) con la distribución de amplitud compleja de la onda en el plano imagen(campo ondulatorio de salida ...

Multivariate Compounds with Equal Number of Summands [PDF]

open access: yes, 2017
[Jordanova Pavlina; Йорданова Павлина]The paper considers multivariate discrete random sums with equal number of summands. Such distributions describe the total claim amount received by a company in a fixed time point. In Queuing theory they characterize

Exact null distributions of quadratic distribution-free statistics for two-way classification

open access: yes, 2004
We present new techniques for computing exact distributions of `Friedman-type¿ statistics. Representing the null distribution by a generating function allows for the use of general, not necessarily integer-valued rank scores.

Inference on the parameters of the Weibull distribution using records

open access: yes, 2020
The Weibull distribution is a very applicable model for lifetime data. In this paper, we have investigated inference on the parameters of Weibull distribution based on record values.

On point estimators for Gamma and Beta distributions

open access: yes, 2022
Let $X_1,\ldots,X_n$ be a random sample from the Gamma distribution with density $f(x)=\lambda^{\alpha}x^{\alpha-1}e^{-\lambda x}/\Gamma(\alpha)$, $x>0$, where both $\alpha>0$ (the shape parameter) and $\lambda>0$ (the reciprocal scale parameter) are ...

Inequalities for quantiles of the chi-square distribution

open access: yes, 2010
We obtain a new sharp lower estimate for tails of the central chi-square distribution. Using it we prove quite accurate lower bounds for the chi-square quantiles covering the case of increasing number of degrees of freedom and simultaneously tending to ...
