Interpret prediction interval
Note that in the formula for the predictive confidence interval no mention is made of the unobservable parameters μ and σ of population mean and standard deviation – the observed sample statistics and of sample mean and standard deviation are used, and what is estimated is the outcome of future samples. Rather than using sample statistics as estimators of population parameters and applying confid… WebIn Meta-Essentials, the larger, green, interval around the combined effect size on the bottom row of the forest plot is the prediction interval ().
