I was hoping there was a formulaic approach, in much the same way that multiple formulas can be layered into a FecObj.</div><div class=""><br class=""></div><div class="">Speaking of FecObj, is there a recommended resource for understanding makeFecObj? The help page describes the "what" of the many options, but is limited on the "why" or "how." The most comprehensive treatment I've found so far is in chapter 3 of the Appendix you recommended, but that is still for a specific use case, and not all the used options are described (e.g., it is unclear how the constants fec2 through fec4 get applied). For a relatively simple use case I had to do some guessing, and then checking the resulting Fmatrix against an offline calculation; I still don't understand how all the parts work together.</div><div class=""><br class=""></div><div class="">Thanks,</div><div class="">Bruce</div><div class=""><br class=""><div><blockquote type="cite" class=""><div class="">On May 26, 2016, at 1:57 PM, Cory Merow <<a href="mailto:cory.merow@gmail.com" class="">cory.merow@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class=""><span style="font-size:12.8px" class="">Hi Bruce,</span><div style="font-size:12.8px" class="">You're on the right track, but you don't have to dig into the Pmatrix slots.
