comment Why do Solve, NSolve, and FindRoot all fail on this simple, solvable actuarial equation?
Brent method proved very useful.

that's a perfectly good method for integer Median LEs, thank you. I'm trying to think of how to generalize it for non-integer LEs and Mean LEs.

@Simon Woods the Ragged Transpose solution in the other thread is exactly what I had in mind.

comment Removing trailing zeros from a list
Checking closely, it appears that some of the "Null" entries in my actual data are "", not Null. I adjusted your code accordingly. Thanks.

Yes, thanks. I need to apply this in an automated way, so I implemented a brute-force-ish method that works. I wonder, if questions of this sort are posted weekly, if Wolfram might change the error messages produced by these functions to be more useful, and/or write about these issues more directly in their documentation.

For beginners, the latter command is shorthand for Map[Last[#]&,list]
