- python - Understanding scipy. stats. norm. rvs ()? - Stack Overflow
In scipy stats norm rvs() the argument scale denotes standard deviation but in the below piece of code sigma_list refers to an array How does the code actually work?
- RVS in SCIPY Python - Stack Overflow
In scipy stats most of distribution have rvs method, which provides random samples But I didn't find explanation random samples of what? probability? No, because it more than 1
- What are the arguments for scipy. stats. uniform? - Stack Overflow
uniform rvs(loc=5, scale=45) Even though it's possible to call the distribution directly with parameters, scipy stats has the following logic:
- Where is scipy. stats. dirichlet_multinomial. rvs? - Stack Overflow
Is the above implementation correct? This looks correct to me Based on the discussion in the PR implementing multinomial, SciPy did implement a bit of code to generate samples from a multinomial Dirichlet, but the code is only part of a test, not a public API One of the reviewers briefly touches on what you mention: optional, probably follow-up PR add RVS method (as demonstrated in test
- python - Difference between random draws from scipy. stats. . . . rvs and . . .
It seems if it is the same distribution, drawing random samples from numpy random is faster than doing so from scipy stats - rvs I was wondering what causes the speed difference between the two?
- python - scipy. stats seed? - Stack Overflow
60 I am trying to generate scipy stats pareto rvs (b, loc=0, scale=1, size=1) with different seed In numpy we can seed using numpy random seed (seed=233423) Is there any way to seed the random number generated by scipy stats Note: I am not using numpy pareto because I want to give different values for scale
- scipy, lognormal distribution - parameters - Stack Overflow
The distributions in scipy are coded in a generic way wrt two parameter location and scale so that location is the parameter (loc) which shifts the distribution to the left or right, while scale is the parameter which compresses or stretches the distribution For the two parameter lognormal distribution, the "mean" and "std dev" correspond to log (scale) and shape (you can let loc=0) The
- Pseudorandom Number Generator - Exponential Distribution
Since you have access to a uniform random number generator, generating a random number distributed with other distribution whose CDF you know is easy using the inversion method So, generate a uniform random number u in [0,1) range, then calculate x by: x = log(1-u) (-λ) x = log(1-uniformRand(0, 1)) (-λ) where λ is the rate parameter of the exponential distribution Now, x is a random
