bife_control(dev_tol = 1e-08, rho_tol = 1e-04, conv_tol = 1e-06, iter_max = 100L, trace = FALSE)
dev_tol |
tolerance level for the first stopping condition of the maximization routine. The
stopping condition is based on the relative change of the deviance in iteration r
and can be expressed as follows: Δ dev / (0.1 + dev) < tol. Default is |
rho_tol |
tolerance level for the stephalving in the maximization routine. Stephalving only takes
place if the deviance in iteration r is larger than the one of the previous iteration. If
this is the case,
||Δ β|| is
halfed until the deviance is less or numerically equal compared to the deviance of the previous
iteration. Stephalving fails if the the following condition holds: ρ < tol,
where ρ is the stepcorrection factor. If stephalving fails the maximization
routine is canceled. Default is |
conv_tol |
tolerance level that accounts for rounding errors inside the stephalving routine when
comparing the deviance with the one of the previous iteration. Default is |
iter_max |
unsigned integer indicating the maximum number of iterations in the maximization
routine. Default is |
trace |
logical indicating if output should be produced in each iteration. Default is |
The function bife_control
returns a named list of control
parameters.
