In summary, The Exponential distribution moment generating function is a mathematical function used to find the moments of an Exponential distribution, such as the mean, variance, and other properties. To find the mean using this function, the first derivative is taken at t=0. It is clos...

So, when scale is taken as 1, then according to the IQR method, any data which lies beyond 2.025σ from the mean (μ), on either side, shall be considered as outlier. But as we know, the data is useful up to 3σ on either side of the μ. So we can’t take scale = 1, ...
