SpikeAndSlabPrior.deterministic_scale#
- SpikeAndSlabPrior.deterministic_scale: float#
Prior standard deviation of the unshrunk rows, in residual-scale units.
The intercept, any trend, and any exogenous regressor of equation \(i\) get variance \((\text{deterministic\_scale} \cdot s_i)^2\), held fixed across sweeps and never subject to exclusion. Must be positive.
