Hi all please i need to know how to generate a Poisson distributed number using the built-in function (poissrnd).use this command to generate 5000 numbers and use maxlikelihood estimate for poission distribution to complete its means

Those instructions are pretty clear. Could you show us what you've coded so far?

[mubashar ali]

sir i did not know how to solve it

please help me for writing this code

[Torsten]

You are not able to solve the problem after reading

?

Here's a link to the documentation for poissrnd().

https://www.mathworks.com/help/stats/poissrnd.html

Scroll down to the "Examples" section and learn how to use that function.

I know it can be intimidating but take it step-by-step. You got this!

[mubashar ali]

could any body write the total code for me

i will b very thankfull

[Adam Danz]

If you get it started and can explain where you got stuck (and share your code), I'd be glad to help out.

lambda = 0:2:10000 r = poissrnd(lambda) now what is the next step

That's not how I interpreted part-1 of your problem.

" i need to know how to generate a Poisson distributed number using the built-in function (poissrnd).use this command to generate 5000 numbers "

I suppose you should choose one value for your lambda and create 5000 random poisson numbers based on that single lambda.

lambda = 100; 
r = poissrnd(lambda, 1,5000);
histogram(r)  %look at the distribution (centered at lambda)

Part-2 of your assigment is to "use maxlikelihood estimate for poission distribution to complete its means"

To achieve that, follow the recommendations by Torsten to read the documentation for poissfit().
