Treatment Weights for τ MRD
Weights w r and w m reflect the probabilities for observing a
subject at the R‐ or M‐frontiers
w M
=
∫
r ≥r c
f (r,m = m c
)dr
∫ f (r = r c
,m)dm + ∫ f (r,m = m c
)dr
m≥m c
r ≥r c
∫
m≥ m c
f (r = r c
,m)dm
w R
=
∫ f (r = r c
,m)dm + ∫ f (r,m = m c
)dr
However, note m≥m that c weights are sensitive r ≥r c to the scaling and
distribution of the assignment variables.
