I'm ok with the notions of component and marginal VaR but can't retrieve
results from marginal.
First what is the PortfolioVaR with the portfolio_method="marginal" ?
Except the sign, the 2 figures I get from these functions for PortfolioVaR
are differents :

is the 5th marginal) :
Many thanks for any helpful comment,
PS : tsdata is any valid timeSeries.
