AI Thread Summary
The Poisson distribution operates within the probability space of non-negative integers (0, 1, 2, 3, ...). In this context, the probability of each integer is defined by the Poisson formula, allowing for the calculation of probabilities for any subset of integers. The sigma algebra for this probability space is indeed the power set of the integers. Clarifications were made regarding the definitions of "distribution" and "probability space." The discussion emphasizes the relationship between the Poisson distribution and its corresponding probability space structure.

probability spaces!

hi!
given poisson distribution in the space 0,1,2,3,... can we check if the distribution is a probability space where sigma algebra is the power set!

You seem to be confused about definitions of terms: "distribution", "probability space".

For the Poisson distribution, the Pr. space is the set of integers, where the probability of a specific integer is determined by the Poisson. Any collection of integers has a probability defined by adding up the prob. of the integers in the set. Thus the power set is the sigma algebra.
 
thanks..i guess my qn was not at all specific..sorry!
 
I was reading documentation about the soundness and completeness of logic formal systems. Consider the following $$\vdash_S \phi$$ where ##S## is the proof-system making part the formal system and ##\phi## is a wff (well formed formula) of the formal language. Note the blank on left of the turnstile symbol ##\vdash_S##, as far as I can tell it actually represents the empty set. So what does it mean ? I guess it actually means ##\phi## is a theorem of the formal system, i.e. there is a...
