A Class of Estimators for Estimating the Variance of the Ratio Estimator

open access: yesJOURNAL OF THE JAPAN STATISTICAL SOCIETY, 2004
Summary: We have proposed a class of estimators for the variance of the ratio estimator which includes two standard estimators \(V_0\), \(V_2\) and the estimators \(V_H\) and \(V_3\) suggested by \textit{R. M. Royall} and \textit{K. R. Eberhardt} [Sankya, Ser. C 37, 43--52 (1975; Zbl 0335.62007)] and \textit{C. F.

Estimating cardiac output from coronary CT angiography: an individualized compartment model in comparison to the Stewart–Hamilton method

open access: yesFrontiers in Cardiovascular Medicine, 2023
BackgroundAttenuation is correlated with the concentration of contrast medium (CM) in the arteries. The cardiac output (CO) affects the concentration of CM in the circulatory system; therefore, CO affects the time–density curve (TDC). Thus, estimating CO
