Answer #2: Probability is about going forward; Statistics is about going backward. Probability is about the process of generating (simulating) data given a value of θ θ. Statistics is about the process of taking data to draw conclusions about θ θ. Disclaimer: the above are mathematical answers.
680. The wikipedia page claims that likelihood and probability are distinct concepts. In non-technical parlance, "likelihood" is usually a synonym for "probability," but in statistical usage there is a clear distinction in perspective: the number that is the probability of some observed outcomes given a set of parameter values is regarded as ...
I would recommend two books not mentioned, as well as several already mentioned. The first is E.T. Jaynes "Probability: The Logic of Science." It is polemic and he is a very partisan author, but it is very good. The second is Leonard Jimmie Savage's "The Foundations of Statistics."
I think it should be an iterative process for most people: you learn a little probability, then a little statistics, then a little more probability, and little more statistics etc. For instance, take a look at the PhD Stat requirements at GWU. The PhD level Probability course 8257 has the following brief description: STAT 8257. Probability. 3 ...
In probability and statistics, a probability distribution assigns a probability to each measurable subset of the possible outcomes of a random experiment, survey, or procedure of statistical inference. Examples are found whose sample space is non-numerical, where the distribution would be a categorical distribution.
12. The vertical bar is often called a ' pipe '. It is often used in mathematics, logic and statistics. It typically is read as 'given that'. In probability and statistics it often indicates conditional probability, but can also indicate a conditional distribution. You can read it as 'conditional on'. For example the third line can be read "pi ...
Connecting 2 different meanings of "degree of freedom". probability. mathematical-statistics. variance. degrees-of-freedom. t-distribution. Glen_b. 289k. answered 1 hour ago.
7. I suggest you a couple of books that I admit I never had the occasion to study. These would have been my reference if I specialized in probability: Ash, Dade - "Probability and Measure Theory". Billingsley - "Probability and Measure". I think (2) is more popular.
In statistics, θ, the lowercase Greek letter 'theta', is the usual name for a (vector of) parameter (s) of some general probability distribution. A common problem is to find the value (s) of theta. Notice that there isn't any meaning in naming a parameter this way. We might as well call it anything else.
0. From my point of view the main difference between proportion and probability is the three axioms of probability which proportions don't have. i.e. (i) Probability always lies between 0 and 1. (ii) Probability sure event is one. (iii) P (A or B) = P (A) +P (B), A and B are mutually exclusive events. Share.
