DESCRIPTION:Inferring causal relations of a system is a fundamental proble
m of statistics. A widely studied approach employs structural causal model
s that model noisy functional relations among a set of interacting variabl
es. The underlying causal structure is naturally represented by a directed
graph whose edges indicate direct causal dependencies. Under the assumpti
on of linear relations with homoscedastic Gaussian errors this causal grap
h and\, thus also\, causal effects are identifiable from mere observationa
l data. Over the past decade\, two main lines of research evolved\, learni
ng the causal graph as well as estimating causal effects when the graph is
known. However\, a two-step method\, that first learns a graph and then t
reats the graph as known yields confidence intervals that are overly optim
istic and can drastically fail to account for the uncertain causal structu
re. In this talk\, I will address this issue and present a framework based
on test inversion that allows us to give confidence regions for total cau
sal effects that capture both sources of uncertainty: causal structure and
numerical size of nonzero effects.\n\nhttps://conference2.aau.at/event/13
