bias-corrected bootstrap method -回复 (假设读者已经有一定的统计学基础知识) 介绍: 假设检验是统计学中非常重要的概念之一,用于判断在某种假设条件下,观测数据与假设是否一致。然而,传统的假设检验方法在某些情况下可能会出现一些问题,比如数据的分布非常偏斜或假设条件不满足时。为了克服这些问题,可以使用一种被称为...
A bias-corrected bootstrap procedure for the estimation of half-life is proposed, adopting the highest density region (HDR) approach to point and interval estimation. The Monte Carlo simulation results reveal that the bias-corrected bootstrap HDR method provides an accurate point estimator, as well...
The bias-corrected GMM estimator is then found by calculating: ˆθBCGMM = ˆθGMM − ¯θ∗ + ˆθa. (13) When both n and B go to infinity, ˆθa will converge to ˆθGMM , so asymptotically this method will produce the same results as the other bootstrap techniques ...
This results in DL-corrected MJO predictions in 1997. For the target year 1998, MJO events from the rest of the 19 years (1997 and from 1999 to 2016) are used to train the LSTM model, and so on. The LSTM model is built at every target year, forecast lead time, MJO phase, and ...
We found a cluster of time points in which a representation of the initial decision was activated earlier in the post- compared with the pre-decision phase when confidence was high (p = 0.01, corrected for multiple comparisons; Fig. 4d). Such early reinstatement of a later processing ...
Therefore, we do not believe that bootstrap methods to produce verification bias corrected confidence intervals are appropriate. We have described the application of certain statistical methods in the presence of verification bias, and the problems with these methods when the analysis data set contains...
ADHD symptoms as well as the symptom clusters by memory bias. Mediation was tested using the PROCESS macro for SPSS (Hayes2013). A bootstrapping method was used to assess the indirect effect based on 1000 bootstrapped samples using bias-corrected and accelerated 95% confidence intervals (BCa CI...
As our model (Eq. (3)) tends to generate homogeneous residuals, the bootstrap method introduced by Efron (1979) can be used to assess the model parameter uncertainty. Study area and data As a demonstration, the framework described in the previous sections was applied to the Flinders and Gi...
The resulting bias-corrected estimate is then given byβ̂−N−1−1ŴN−1B̂N+D̂N. It is possible to show that these plug-in corrections lead to estimates that are asymptotically unbiased as N → ∞. Still, for finite samples, it is evident that the bias in some ...
