    Maximum Likelihood Estimation error calculations

    I have a question about calculating standard error in MLE. For the simplicity, I will describe the idea on a simple sample, but in real life I have a problem, which can be solved only with MLE. Consider we have 1000 integer numbers (so-called outcomes) generated with Poisson distribution with...

    Finding the probability of committing a type II error

    I'm not sure If I understand what (b) is asking. Does it mean that the alternative hypothesis will be p<0.3, p<0.4, and p<0.5??? And I have to find the probability of committing a type 2 error for each alternatives? If I am right then the setup that I have for p=0.3 in part (b) is correct.

    Error estimation with the integral test

    How did they get 1/1029 and 1/648? They used the sequence 1/n^4 right? But I don't know what they plugged in for n to get those 2 fractions. Also it says that it is known that the summation of 1/n^4 from 1 to infinity is equal to pi^4/90. How did they get pi^4/90?

    standard error of prediction very small for models with almost no correlation

    Hello, I have been tracking the change in various statistics over epochs of learning in an artificial neural network model. I notice that the standard error of prediction for the validation set (STEYX() in excel), is always very low over the first 15 epochs or so. A low standard error implies a...

    Find the error in the following argument

    Find the error in the following argument by providing a counterexample. “The reflexive property is redundant in the axioms for an equivalence relation. If x ∼ y, then y ∼ x by the symmetric property. Using the transitive property, we can deduce that x ∼ x.”
