Hi
I don t know if you already get answers for the above questions.
For the +/* operators, we should respectively refers to RandomMixture &
ProductDistribution for more details
import openturns as ot
a = ot.Normal() b = ot.LogNormal() #c = a*b ==> ProductDistribution
distribution — OpenTURNS documentationc = ot.ProductDistribution(a, b)
# d = a + b ==> RandomMixture — OpenTURNS documentation
| |
d = ot.RandomMixture([a, b])

curious about the methods used for random variable algebra in OpenTurns; that
is, what are the mathematics / pseudocode used for adding/subtracting and
multiplying or dividing Distribution objects? For example, a = ot.Normal() b =
ot.LogNormal() c = a*b When calculating probabilities of failure using a
limit state function, are there guidelines for when it is faster and/or more
accurate to write the limit state function as an algebraic expression of the
random variables compared to using FORM or SORM with a Function or
NumericalMathFunction? Thanks, Phil
