Asymmetric smooth transition autoregressive model in forecasting finance rate on consumer installment loans at commercial banks [PDF]

Journal of Mahani Mathematical Research
Economic and finance time series are typically asymmetric and are expected to be modeled using asymmetric nonlinear time series models. The logistic smooth transition autoregressive, LSTAR, model which is an asymmetric type of the smooth transition ...

Bias Reduction of Maximum Likelihood Estimates for an Asymmetric Class of Power Models with Applications

Revstat Statistical Journal, 2023
In this paper we study some methods to reduce the bias for maximum likelihood estimation in the general class of alpha power models, specifically for the shape parameter. We find the modified maximum likelihood estimator using Firth's method and we show

Influence of the Determination Methods of K and C Parameters on the Ability of Weibull Distribution to Suitably Estimate Wind Potential and Electric Energy

International Journal of Renewable Energy Development, 2014
The modeling of the wind speed distribution is of great importance for the assessment of wind energy potential and the performance of wind energy conversion system. In this paper, the choice of two determination methods of Weibull parameters shows theirs

Approximate maximum likelihood estimation of two closely spaced sources [PDF]

, 2014
The performance of the majority of high resolution algorithms designed for either spectral analysis or Direction-of-Arrival (DoA) estimation drastically degrade when the amplitude sources are highly correlated or when the number of available snapshots is

Ricean Bias Correction in Linear Polarization Observation [PDF]

Journal of Astronomy and Space Sciences, 2011
I developed an enhanced correction method for Ricean bias which occurs in linear polarization measurement. Two known methods for Ricean bias correction are reviewed. In low signal-to-noise area, the method based on the mode of the equation gives better

Odds Ratio Estimation for Small Count in Zero-Inflated Poisson

IEEE Access, 2020
The odds ratio estimation when observed frequencies are very small usually causes difficulty in calculation. In this paper, we proposed the estimator of odds ratio for small count using Empirical Bayes (EB) in Zero-inflated Poisson distribution, where ...
