What is the estimated number of animals in a forest using a Poisson model?

I am not sure which distribution this is:
there are N animals in a forest, we don't know N but would like to estimate it... so, I need to select a model (distribution)

ps: i am trying to avoid Normal distribution...
 
Physics news on Phys.org
Are you permitted to capture and mark animals? If yes, using hypergeometric distbn. we can estimate N.
 
doesn't say anything about marking, i think they just count it in an area over time, that's my assumption, but the problem does not say. So, perhaps Poisson?
 

Thread 'Here's a Statistics problem for game of Polo (or Hockey if you like)'

Namaste & G'day Postulate: A strongly-knit team wins on average over a less knit one Fundamentals: - Two teams face off with 4 players each - A polo team consists of players that each have assigned to them a measure of their ability (called a "Handicap" - 10 is highest, -2 lowest) I attempted to measure close-knitness of a team in terms of standard deviation (SD) of handicaps of the players. Failure: It turns out that, more often than, a team with a higher SD wins. In my language, that...

Thread 'Roulette wheel physics and probability'

Hi all, I've been a roulette player for more than 10 years (although I took time off here and there) and it's only now that I'm trying to understand the physics of the game. Basically my strategy in roulette is to divide the wheel roughly into two halves (let's call them A and B). My theory is that in roulette there will invariably be variance. In other words, if A comes up 5 times in a row, B will be due to come up soon. However I have been proven wrong many times, and I have seen some...
