The distribution has a PDF given by:
-f(x) = (1/scale) e[super -(x-location)/scale] e[super -e[super -(x-location)/scale]]
+[expression f(x) = (1/scale) e[super -(x-location)/scale] e[super -e[super -(x-location)/scale]]]
-Which in the standard case (scale = 1, location = 0) reduces to:
+which in the standard case (scale = 1, location = 0) reduces to:
-f(x) = e[super -x]e[super -e[super -x]]
+[expression f(x) = e[super -x]e[super -e[super -x]]]
The following graph illustrates how the PDF varies with the location parameter:
[[kurtosis excess][kurtosis - 3 or 12 / 5]]
