smooth.OM.sigma

property OM.sigma: float

sqrt(mean(residuals²)).

Matches R’s sigma.om (R/om.R): the OM residuals live on the link-transformed scale (logit / log-odds), so their second moment is a meaningful scale parameter for the underlying ETS, even though there’s no equivalent on the probability axis.

Returns NaN only if the model has no residuals yet (e.g. constructed but not fitted).

Type:

Link-scale residual std-dev
