Summary for a cross-family Julia fit

The cross-family route (drmTMB(bf(...), c(fam1, fam2), engine = "julia"), via drm_julia_call_xfam() -> DRM.fit_mixed_family) is reachable from R and tested (tests/testthat/test-xfam-bridge.R), but its capability-ledger status is experimental/partial (inst/extdata/julia-capabilities.tsv, cross_family_latent). This summary reports point estimates only: the bridge does not retain a named covariance matrix, so standard errors and Wald intervals are deliberately unavailable.

Usage

# S3 method for class 'drmTMB_julia_xfam'
summary(object, conf.int = FALSE, ...)

Arguments

object

A drmTMB_julia_xfam cross-family fit.

conf.int

Logical; requesting intervals errors because the bridge did not return fixed-effect covariance.

...

Unused.

Value

An object of class summary.drmTMB_julia containing point estimates and an explicit unavailable-uncertainty status.
