... Loosely speaking, there is an x% probability that your future data will fall in your x% confidence interval for the forecast—but only if your model and its underlying assumptions are correct and the sample size is reasonably large. This is why we test model assumptions and why we should be cautious ...

... The sum of squared deviations from the mean is calculated for each sample separately and then pooled, that is, added, and the average squared deviation across both samples is calculated by dividing by the combined degrees of freedom. The Pooled Standard Deviation is the square root of this. Why are ...

The horizontal black line shows the mean under the null hypothesis (i.e. 0) and the horizontal bold red line shows the sample mean paired difference. The horizontal dashe ...
