Check sustained feasibility over future n — .sustained_singlearm

Given vectors of operating characteristics over n, check whether power, type-I-error, and CE(H0) satisfy their thresholds at n and for at least sustain_n subsequent sample sizes.

Usage

.sustained_singlearm_feasibility(
  n_vec,
  power_vec,
  type1_vec,
  ce_vec,
  target_power,
  target_type1,
  target_ce,
  sustain_n
)

Arguments

n_vec: Integer vector of sample sizes.
power_vec: Numeric vector of power values (same length as n_vec).
type1_vec: Numeric vector of type-I-error values.
ce_vec: Numeric vector of CE(H0) values (may contain NA).
target_power: Numeric target power.
target_type1: Numeric target type-I-error.
target_ce: Numeric target CE(H0); if <= 0, CE constraint is ignored.
sustain_n: Integer, number of subsequent sample sizes that must also satisfy the constraints.

Value

Logical vector of length length(n_vec): TRUE if n_i and the next sustain_n sample sizes satisfy all active constraints.
