Bootstrapping VAR(p) model: bias-correction based on the bootstrapJae H. Kim
This paper examines small sample properties of alternative bias-corrected bootstrap prediction regions for the vector autoregressive (VAR) model. Bias-corrected bootstrap prediction regions are constructed by combining bias-correction of VAR parameter estimators with the bootstrap procedure. The backward VA...
Parameter estimates for each path (a, b, c, a × b, c’) were obtained by bootstrapping 200,000 times with replacement, producing two-tailed p-values and 95% confidence intervals. In a control model in which the predictor and mediator variables were swapped, no mediation effect was...
to obtain an unbiased average estimate of the ratio, we calculated the respective mean of the distribution, while to obtain the 95% Confidence Intervals (CIs) around the mean, we considered the quantile method as is usual in non-parametric bootstrapping. All the statistical analyses were perform...
We performed a simulation experiment where we repeated steps A and B 2000 times and report the mean of the true and verification bias corrected AUC, as well as the 2.5th –97.5th percentiles and coverage. Coverage was the proportion of 95% confidence intervals, constructed using bootstrap meth...
In this study, all the confidence intervals at the 95% level were also created with bootstrapping. 2 4.1. Correction results for 2m-T --> 4.1. Correction results for 2m-T Figure 5 shows the RMSE spatial distribution of the corrected 24 h forecast for 2m-T in all seasons in 2018. ...

Bootstrapping for the statistical test of model parameter changes To examine whether the mean change in a parameter acrossNdifferent inactivation sessions is significantly different from zero, we randomly drewNvalues from the originalNobservations allowing repetitions, computed the mean ofNrandom samples,...
