Explain instances where we have to use the Bootstrap tool in Crystal Ball

What will be an ideal response?


The classical approach for confidence intervals assumes that the sampling distribution of the mean is normal. However, if the sampling distribution is not normally distributed, such a confidence interval is not valid. Also, if we wanted to develop a confidence interval for the median, standard deviation, or maximum forecast value, for example, we may not know the sampling distribution of these statistics.
Bootstrapping analyzes sample statistics empirically by repeatedly sampling the data and creating distributions of the statistics. This approach allows you to estimate the sampling distribution of any statistic, even an unconventional one such as the minimum or maximum endpoint of a forecast.
