I want to generate a number based on a distributed probability. For example, just say there are the following occurrences of each numbers: Number| Count 1 | 150 2 | 40 3 | 15 4 | 3 with a tot...

I have read some papers regarding to non-iid data. Based on Wikipedia, I know what iid (independent and identical distributed) data is but am still confused about non-iid. I did some research but c...

I have a support (supp_epsilon) and a probability mass function (pr_mass_epsilon) in Matlab, constructed as follows. supp_epsilon=[0.005 0.01 0.015 0.02]; suppsize_epsilon=size(supp_epsilon,2); ...

What is the difference between causal models and directed graphical models? What is the difference between causal relationships and directed probabilistic relationships? More concretely, what would...

How does tf.multinomial work? Here is stated that it "Draws samples from a multinomial distribution". What does that mean?

Currently taking a course on decision analysis. There is a concept called "flipping a probability tree", illustrated in the following example. May I know: (1) Is there a way to do the above gra...

I'm trying to create a percentage-based probability for a game. E.g. if an item has a 45% chance of a critical hit, that must mean it is 45 of 100 hits would be critical. First, I tried to use a s...

This picture from Wikipedia has a nice example of the sort of functions I'd ideally like to generate: Right now I'm using the Irwin-Hall Distribution, which is more or less a polynomial approxim...

I want to ask you about the notation in probability. I know that P(A | B) = the conditional probability that event A occurs given that event B has occurred already But I cannot find w...

Given a mean and standard-deviation defining a normal distribution, how would you calculate the following probabilities in pure-Python (i.e. no Numpy/Scipy or other packages not in the standard lib...

I have a probability problem, which I need to simulate in a reasonable amount of time. In simplified form, I have 30 unfair coins each with a different known probability. I then want to ask things ...

I'm trying to determine how my crc compares to an "ideal" 32bit crc. So I ran my crc over 1 million completely random samples of data and collected the amount of collisions, I want to compare thi...
