Description Usage Arguments Value See Also Examples
This function is a transformation function that takes the log of the log of the inverse (which can be used to generate the Prelec functions). By design, it is robust to the inclusion of the occasional 0, which it maps to a very small value, which can optionally be specified It's appropriate for mapping (0, 1):-> (-inf, inf).
