Estimate the corrupted signal strength in a model with (sub-)Gaussian covariates

The Signal Strength Leave-One-Out Estimator (SLOE) is defined in
Yadlowsky et al. (2021) when the model is estimated using maximum
likelihood (i.e. when object$alpha = 1
; see mdyplControl()
for
what alpha
is). The SLOE adaptation when estimation is through
maximum Diaconis-Ylvisaker prior penalized likelihood
(mdypl_fit()
) has been put forward in Sterzinger & Kosmidis
(2025).
In particular, sloe()
computes an estimate of the corrupted
signal strength which is the limit
\nu^2
of var(X
\hat\beta(\alpha))
, where \hat\beta(\alpha)
is the maximum
Diaconis-Ylvisaker prior penalized likelihood (MDYPL) estimator as
computed by mdyplFit()
with shrinkage parameter alpha
.
A scalar.
