K_adj — pop_model_K_adj • CEMPRA

Define K_adj value. DEPRECATED legacy pathway.

Usage

pop_model_K_adj(
  replicates = 100,
  dat,
  mx,
  dx,
  Nyears = 250,
  H.mx = NULL,
  K = NULL
)

Arguments

replicates: Number of replicates
dat: Life history data
mx: A projection matrix expression
dx: A matrix of density-dependence effect
Nyears: Years to run simulation (must be greater than 51)
H.mx: A harm projection matrix
K: Adult carrying capacity being calibrated. Defaults to dat$Ka for backwards compatibility; Projection_DD passes its own K argument so the calibration measures the same model it is calibrating.

Value

A K_adj object to make adjustments

Details

DEPRECATED: this is a legacy stochastic capacity calibration retained for backwards compatibility with older scripts. It is never called by PopulationModel_Run or the Shiny app, is only meaningful in compensation-ratio mode, and is deliberately not exercised by the test suite (the replicate simulations are slow). Repaired 2026-09-15 (previously received NULL projection matrices from Projection_DD and crashed).

Runs replicate stochastic simulations, measures the realized long-run mean adult abundance, and returns K.adj = K / mean so callers can inflate the working capacity (stochastic variability drags the long-run mean below the deterministic K). A 51-year burn-in is discarded from each replicate, so Nyears must exceed 51.
