Select the phase whose log_mu will be solved by conservation

Chooses the phase contributing the largest share of total cumulative hazard, matching the C HAZARD SETCOE strategy.

Usage

.hzr_select_fixmu_phase(
  theta,
  time,
  status,
  phases,
  covariate_counts,
  x_list,
  weights = NULL
)

Arguments

theta

Full parameter vector (internal scale).

time

Numeric vector of follow-up times.

status

Numeric event indicator.

phases

Named list of validated hzr_phase objects.

covariate_counts

Named integer vector.

x_list

Named list of per-phase design matrices.

weights

Optional numeric vector of row weights (length n). Defaults to unit weights. Applied when summing per-phase cumhaz so that selection happens on the same scale as the (weighted) observed event count.

Value

Character: name of the phase to fix.
