Why can’t ALL actuarial early retirement pension factors be calculated accurately instead of only discrete accurate factors being tabulated with ‘in-between’ ones being interpolated?
Because accuracy is meaningless in this context.
Is this really different from the question you asked here?
I also see you’ve started 15 or so threads on mortality curves on a site called the “Actuarial Outpost”, would that be a better reference than the SDMB? I assume there are practicing actuarials there.
You’ve also been posting about mortality curves (or someone with your name and interests) on a place called “GoActuary”, which sounds like a command to depart, or an energetic encouragement.
Just trying to help you get to a satisfactory answer here.
