This is the data table I am working with.
This is the formula I need to apply in Excel.
I want to clarify some notations. k_p_x means the probability that the individual aged x will survive for the next k years.
p_x would simply assume k=1. And is the probability of surviving for the next 1 year. And obviously k_p_x can be computed using these single year probabilities.
In my datatable in Excel I have all of the single year probability of survival.
However, in my formula I need to add multiple iterations of k_p_x which makes this a little complicated.
Does anyone have any idea how to do this in Excel?
Or should I use Rstudio instead?
I tried playing around with SUM() with PRODUCT() inside. But I am not sure how to reiterate k_p_x for k=1,2,3... up to like 100.
