1. σ2^β1=1nVar[(Xi−μX)ui][Var(Xi)]2.

This formula is wrong. It should be as follows: $$Var(\hat{\beta}1) = \frac{\sum{i=1}^N Var(x_i - \bar{x})^2 u_i}{(Var(\sum_{i=1}^N (x_i - \bar{x})^2))}$$

Otherwise, $\sigma_{\hat{\beta}_1}$ is different for each $u_i$.

1. probability compounds

compound probability = 1 - (1 - annual probability of excedence)^n where:

• annual probability = 0.01
• n = exposure period = 10 years

by other hand Mean Recurrence Interval - MRI = Return Period = 1 / annual probability of exceedence, but only if MRI >= 10 years, if not then:

annual probability of excedence = 1-e(-1/MRI)
