The larger the \(\lambda\) is, the more you prefer the \(\beta_j\)'s close to zero. In the extreme case when \(\lambda = 0\), then you would simply be doing a …
WebThe computation of the MLE of $\lambda$ is correct. The consistency is the fact that, if $(X_n)_{n\geqslant1}$ is an i.i.d. sequence of random variables with exponential distribution of parameter $\lambda$, then $\Lambda_n\to\lambda$ in probability, where $\Lambda_n$ denotes the random variable $$ … Web• Calculate z = (x −0.5− θ)/ √ θ. • Find the area under the snc to the right of z. If θ is unknown we can use the value of X to estimate it. The point estimate is x and, following the presentation for the binomial, we can use the snc to obtain an approximate confidence interval for θ. The result is: x± z √ x. 34
