Thanks for the reply and sorry about my absence.
An example dataset would simply be:
Load * Inline
Essentially these are parameters for NPV. I am missing the payments and want to extrapolate them using the other terms. Y is the NPV, b is the discount, and i is the life of the loan. I can do this mathematically outside of qlik but cant work out a way to do it in a Qlik load script.
Thanks for the attention to this problem.
