In contrast, asymptotic distribution of PMG estimator was obtained for n fixed and T→∞. Allowing for both n and T large seems to be the more relevant empirical setting, as revealed by numerous applications of the PMG estimator in the literature. Dynamic panel estimators are biased when T ...

B. An approximate t-test that involves the calculation of a pooled estimator of the population variances which are assumed unequal. C. A paired comparison test if the two samples are independent and the population variances are unknown. 解析:选A。排除法。B项的方差不相等,因此不能用汇集估计量。

Despite these limitations, the strength of a pooled analysis is that it provides more accurate estimates of injury rates than the individual studies that provided the data.11 Therefore, it can be utilised to compare against other pooled studies to obtain a combined estimator of the quantitative ...
Finally, a density function fitted onto the gene FiPer scores’ observed distribution (which is typically bimodal) using a kernel estimator and the score corresponding to the point of central local minimal density is used as a discriminative threshold to predict CEGs, which will be those with a ...
Present paper deals with the problem of optimum stratification when the parameter of interest is pooled variance. In this paper, an estimator of pooled variance is suggested and minimal equations to get optimum boundary points are obtained by minimizing the variance of the estimator under ...
A pooled log periodogram regression estimator is proposed that utilizes a set of mL periodogram ordinates with L →∞ rather than m ordinates as in the conventional log periodogram estimator. Consistency and asymptotic normality of the pooled regression estimator are established. The pooled ...
In the beginning of the section we introduce some notation. We then present the prior and posterior distribution given the data and derive the state update equations for the TDSPool estimator. We further present the modified partition-ligation procedure adjusted for the pooled data so that we are...
To avoid econometric misspecification, the study also employs for the first time a nonparametric time-varying coefficient panel data estimator with fixed effects (NPFE) for the dataset of 37 oil-producing countries in the time interval spanning between 1989 and 2019. The empirical analysis identifies...
