A Sampling experiment performed using data collected for a large clinical trial shows that the discriminant function estimates of the logistic regression coefficients for discrete variables may be severely biased. The simulations show that the mixed variable location model coefficient estimates have bias ...

Hands from 33 videos originally used for the HAL rating were tracked to estimate S, scaled relative to hand breadth (HB), and single-frame analysis was used to measure D. Since HBs were unknown, a Monte Carlo method was employed for iteratively estimating the regression coefficients from US ...
Reviews the literature and shows that under very general circumstances coefficients in multiple regression models can be replaced with equal weights with almost no loss in accuracy on the original data sample. It is then shown that these equal weights will have greater robustness than least squares ...
(ventilator efficiency) slope (VE–VCO2slope) was based on data from the onset of exercise to the respiratory compensation point, and it was obtained by performing a linear regression analysis of the data acquired throughout the entire period of exercise29,30. The respiration quotients at VT ...

A Monte Carlo study of the small sample properties of various estimators of the linear regression model with first-order autocorrelated errors. When independent variables are trended, estimators using Ttransformed observations (Prais-Winsten) are much more efficient than those using T–1 (Cochrane–...
aA regression in the form of equation (3) is thus equivalent to estimating the “true” equation (5) with the last term omitted. The relation between the estimated coefficients c , and c, of equation (3) and the parameter p of equation 退化以式 (3的形式) 因而是等值到估计“真实的”式...
In this note, we consider the problem of estimating regression coefficients when there are missing observations of some explanatory variables. Following Dagenais (1973), Gourieroux and Monfort (1981), and Conniffe (1983a, 1983b), we assume auxiliary relationships exist among explanatory varibles....
