Hi Hötzi,

❝ Hi ElMeastro,

ElMeastro?? ElMistress? Must be the heat....

❝ ❝ 1. If X~N(μ, σ2) then what is the geometric mean of X?

❝

❝ I would say the general case (for arbitrary u, s²) is not defined since (∏X)^1/N will not work if you have at least one negative value of X in the set.

Very good point. One could ask 'then what if I have an even number of negatives' but I will refrain.

Departure from log-normality might be my next playground ....
