Corrected Maximum Likelihood Estimations of the Lognormal Distribution Parameters

open access: yesSymmetry, 2020
As a result of asymmetry in practical problems, the Lognormal distribution is more suitable for data modeling in biological and economic fields than the normal distribution, while biases of maximum likelihood estimators are regular of the order O ( n − 1

Call center service times are lognormal: A Fokker–Planck description [PDF]

open access: yesMathematical Models and Methods in Applied Sciences, 2018
Call centers are service networks in which agents provide telephone-based services. An important part of call center operations is represented by service durations.

A Statistical Approach to Estimate the Wind Speed Distribution: The Case of Gelibolu Region [PDF]

open access: yes, 2011
Rüzgar enerjisi yenilenebilir ve çevre dostu bir enerjidir. Rüzgar enerjisi atmosferi kirleten fosil yakıtlarıyla kıyaslandığında, temiz enerji kaynağı için bir alternatiftir. Rüzgar enerjisinin potansiyelinin en önemli parametresi rüzgar hızıdır. Rüzgar

Improving lognormal models for cosmological fields [PDF]

open access: yes, 2016
It is common practice in cosmology to model large-scale structure observables as lognormal random fields, and this approach has been successfully applied in the past to the matter density and weak lensing convergence fields separately. We argue that this

Rüzgar hızı dağılımının tahmin edilmesi için istatistiksel bir yaklaşım: Gelibolu bölgesi örneği [PDF]

open access: yes, 2008
Wind energy is renewable and environment friendly. It is an alternative clear energy source compared to the fossil fuels that pollute the lower layer of atmosphere. The most important parameter of the wind energy is the wind speed.
