Estimation of Vehicle Dynamic Parameters Based on the Two-Stage Estimation Method [PDF]

open access: yesSensors, 2021
Vehicle dynamic parameters are of vital importance to establish feasible vehicle models which are used to provide active controls and automated driving control. However, most vehicle dynamics parameters are difficult to obtain directly.

Conditional Estimation in Two-Stage Adaptive Designs [PDF]

open access: yesBiometrics, 2017
Summary We consider conditional estimation in two-stage sample size adjustable designs and the consequent bias. More specifically, we consider a design which permits raising the sample size when interim results look rather promising, and which retains the originally planned sample size when results look very promising.

Two-stage and modified two-stage estimation in threshold first-order autoregressive process [PDF]

open access: yesJournal of Mahani Mathematical Research, 2023
In this paper, we discuss the two-stage and the modified two-stage procedures for the estimation of the threshold autoregressive parameter in a first-order threshold autoregressive model (${\rm TAR(1)}$).

The Robust Variance Estimator for Two-stage Models [PDF]

open access: yesThe Stata Journal: Promoting communications on statistics and Stata, 2002
This article discusses estimates of variance for two-stage models. We present the sandwich estimate of variance as an alternative to the Murphy–Topel estimate. The sandwich estimator has a simple formula that is similar to the formula for the Murphy–Topel estimator, and the two estimators are asymptotically equal when the assumed model distributions ...

Two-Stage Estimation of Nonrecursive Choice Models [PDF]

open access: yesPolitical Analysis, 1999
Questions of causation are important issues in empirical research on political behavior. Most of the discussion of the econometric problems associated with multiequation models with reciprocal causation has focused on models with continuous dependent variables (e.g., Markus and Converse 1979; Page and Jones 1979). Yet, many models of political behavior

Power Families of Bivariate Proportional Hazard Models

open access: yesMathematics, 2022
In this paper, we propose a general class of bivariate proportional hazard distributions, which is based on the family of asymmetric proportional hazard distributions and the bivariate Pareto copula.

TWO-STAGE DEA ESTIMATION OF TECHNICAL EFFICIENCY: COMPARISON OF DIFFERENT ESTIMATORS [PDF]

open access: yesReview of Agricultural and Applied Economics, 2022
Research background: The challenge of resource limitations requires that farmers make judicious use of resources to maximize output and profit levels. This can be achieved through assessment of resource-use efficiency of farmers by estimating the level ...

An Exponentiated Multivariate Extension for the Birnbaum-Saunders Log-Linear Model

open access: yesMathematics, 2022
In this work, a bivariate extension of the univariate exponentiated sinh-normal distribution is proposed. The properties of the new distribution, which is called the bivariate exponentiated sinh-normal distribution, are studied in detail, and the maximum
