Teach me something about statistics...Thank you..
Null hypothesis: OP will learn nothing from this thread
>>16913838in a permutation order matters, in a combination it doesnt $${}_{n}P_{r} = \frac{n!}{(n-r)!}$$
R is programming language for statistics
if someone offers you to pick one of three doors, kick him in the nuts and steal his wallet
Frogniggers are statistically low effort posters.
>>16913838Statistically, there is a very high chance that a schizo has posted in this thread by the second post.
>>16913838The variance of the asymptotic distribution of a sum of independent variables need not be the same as the asymptotic variance of the sum.
>>16913838You can do arithmetic on random variables. Sometimes the resulting distributions even have closed-form formulas. For example, if you add two uniform distributions over the same interval you just get a triangular distribution.
>>16914284>if you add two uniform distributionstwo uniform random variables*
>>16914284>if you add two uniform distributionsif you convolute two uniform distributions*
>>16913838Poorly constructed models can cause great harm.
>>1691383810 out of 10 pepefaggots are retarded nigger faggots, hope that helps
>>16914281LMAO @ this NPD psycho still seething all this time later while every single thing I ever posted about here has been proven to be correct, while everything thing that comes out of his face continues, with 100% accuracy to be the stupidest shit you will hear that day. You are a clown, a jester, sadly not even an amusing one, just one of the retarded ones people dont really laugh at, they just point to as a cautionary example of what total failure looks like. The fact that my mere existence makes you seethe uncontrollably brings me great joy
>>16914284>>16914286>>16914287which one is it???
>>16914479The first two are my post and my own correction. The third one is someone else but also true: the convolution of the PDFs of two independent random variables gives the PDF of their sum.
>>16914490oic thank
>>16913838Statistics fags have not discovered or created of note and have spent the last 2-3 decades leaching off machine learning chads and claiming they already knew whatever mlchads do.
>>16913838half coins are neat!https://en.wikipedia.org/wiki/Negative_probabilityhttps://web.archive.org/web/20131108010759/http://www.wilmott.com/pdfs/100609_gjs.pdf
>>16913838You can throw out probability and replace all the foundations of stats with game theory instead https://www.probabilityandfinance.com/
wtf why did you turn purple
>>16913838The CRLB is actually only a special case of a much more general inequality known as the Van Trees/Lehmann Covariance Inequality. This inequality is a natural consequence of Cauchy-Schwarz and can be used to find statistical covariance bounds for arbitrary true sample and modeling distributions.
>>16914479If [math] x_1 \sim p_1(x)[/math] and [math] x_2 \sim p_2(x) [/math] then [math] y = x_1 + x_2 \sim p_y = \int p_1(x)p_2(y-x)dx [/math]
>>16914284nice
>>16914778>muh aikys
>>16913838Suppose X is a random variable, f(x) is the probability density function, and g(X) is an arbitrary function of X, then[math] E(g(X)) = \int_R g(x) f(x) dx[/math]
>>16913838If you fit a regression model for the purpose of inference, don't forget to validate model assumptions. Check QQ-plots, scale-location plots, etc. If you fit a GLM, check that the deviance does not vastly exceed the residual degrees of freedom. If you fit a GL(M)M, the DHARMa package in R is a surprisingly useful diagnostic tool.
>>16913838"first moment" is just a fancy name for "expected value", which in turn is just a fancy name for mean value
>>1691383823% of statistics are made up on the spot.
