Confidence interval for exponentially distributed estimator
We have an estimator $\hat{\theta}\geq 0$ for $\theta$, with distribution function $P\{\hat{\theta}\leq t \}=1-e^{-t/\theta}$, which we can recognize as the cdf of the exponential distribution. Our ...

How to estimate the confidence interval for a "predicted difference" from a quadratic model?
Assume you have past consumption levels $c_1, \dots c_n$ at times $t_1, \dots t_n$ and cumulated consumption levels $y_1=c_1, y_2 = c_1 + c_2, \dots y_n=\sum_{k=1}^{n} c_k$.
(I use the quadratic term ...

Variance estimator of Bernoulli RV (in CI)
Assume n samples from Bernoulli distribution with unknown parameter p,
i. e. $x_{1},....,x_{n}\underset{iid}{\sim}Ber\left(p\right)$
It is known that the confidence interval is given by:
$CI=\hat{...

Why do we examine the rate of convergence when we find a confidence interval?
I would like to help me with this. I don't understand why do we examine the rate of convergence. Also what do we mean by saying "the error is usually dominated by the variance, not the bias"
Thank ...
