TSSCDFName:
This distribution can be extended with lower and upper bound parameters. If a and b denote the lower and upper bounds, respectively, then the location and scale parameters are:
scale = b  a The general form of the distribution can then be found by using the relation
<SUBSET/EXCEPT/FOR qualification> where <x> is a number, parameter, or variable containing values in the interval (a,b); <y> is a variable or a parameter (depending on what <x> is) where the computed twosided slope cdf value is stored; <alpha> is a number, parameter, or variable in the interval (0,2) that specifies the first shape parameter; <theta> is a number, parameter, or variable in the interval (a,b) that specifies the second shape parameter; <a> is a number, parameter, or variable that specifies the lower bound; <b> is a number, parameter, or variable that specifies the upper bound; and where the <SUBSET/EXCEPT/FOR qualification> is optional. If <a> and <b> are omitted, they default to 0 and 1, respectively.
