PRML: Why does the sequential estimation algorithm of normal parameters use $X_N$ but $X_{n-1}$?
I'm reading sequential estimation section 2.3.5 PRML where Bishop introduces Robbins-Monro algorithm to calculate the root of $f(\theta) = E z | \theta = \int zp(z|\theta) dz, (z, \theta) \sim p(z, \...

How many samples do I need to estimate a gaussian distribution?
Background: I'm comparing the performance of two algorithms. The data is noisy so the results tend to form a nice normal distribution.
I'd like to estimate the mean with a high confidence: up to 1% ...

How to compute expected value?
Hi I am trying to compute this:
It's a denominator of ANS function in sequential statistics.The result is:
I set "sigma1"=1 and "mi" is considered as a constant.Do you have any idea how to get the ...
