This solution doesn't account for the point at which the rabbits born in month 2, 3, 4, 5, etc become 4 months old, meaning they can now give birth every month, only the original population, so it assumes all Rabbits "age>3" can all give birth when there should be a delay for every new litter.
I worked this one out in excel first as I'm very new to alteryx (see attached) and it looks to me like your solution may be incorrect. Can you point out where your solution does the following:
- removes the females born in the preceding three months from the previous month's total rabbit population as they are too young to procreate, before calculating the number of males and females that are born in the current month and adding the number onto the previous month's rabbit population for the new total
- subtracts the number of rabbits that die (born in the -24)each month as part of the total rabbit population calculation before feeding into the above
I'm very new to alteryx and I'd love to understand where these elements are in your file.
You had my curiousity, but now you have my attention: why do those conversion errors happen? The field type is set to int64, but the Multi-Row uses a float. However, those values should fit in a float, so: are these floating-point errors? @JoeM?
I see, thanks for this. So they missed the part in the brackets: (Alive months 0-23, die on the start of the 24th month).
As each month is dated the 2nd, by the time the 24th month comes round some rabbits should have died on the 1st day of the month..
