Parameter Estimation in Stable Law

Risks, 2016
For general stable distribution, cumulant function based parameter estimators are proposed. Extensive simulation experiments are carried out to validate the effectiveness of the estimates over the entire parameter space.

Parameter Estimation Strategies in Thermodynamics

ChemEngineering, 2019
Many thermodynamic models used in practice are at least partially empirical and thus require the determination of certain parameters using experimental data.

Estimating the Parameters of a Convolution

Journal of the Royal Statistical Society Series B: Statistical Methodology, 1969
Summary Parametric estimation problems are considered when one observes a random variable which is the sum of two independent non-identically distributed random variables. Some basic identifiability theorems are given which suggest the method of moments as a general method for attacking such problems, particularly when one of the summand

Decoupled Parameter Estimation Methods for Hammerstein Systems by Using Filtering Technique

IEEE Access, 2018
The implementation of parameter estimation of Hammerstein systems is much difficult due to the existing parameter products from the nonlinear block and the linear block. This paper directly decomposes the parameter coupling between the nonlinear part and

The robust estimation of examinee ability based on the four-parameter logistic model when guessing and carelessness responses exist.

PLoS ONE, 2021
The three-parameter Logistic model (3PLM) and the four-parameter Logistic model (4PLM) have been proposed to reduce biases in cases of response disturbances, including random guessing and carelessness. However, they could also influence the examinees who

On Estimating Monotone Parameters

The Annals of Mathematical Statistics, 1968
Suppose for each $i = 1,2, \cdots, k$ the random variable $X_i$ has density function $f(x; \theta_i)$ where each of the parameters $\theta_1, \theta_2, \cdots, \theta_k$ is known to belong to some connected set $\Theta$ of real numbers. Independent random samples are taken from the distributions of $X_1, X_2, \cdots, X_k$ and we wish to find estimates $
