In ingorohlfing/qcapower: Estimate Power and Required Sample Size in QCA

Description

qp_cases_brute calculates the number of cases needed for a particular power level. The function starts with the number of cases given by start_value and iteratively simulates power and adjusts the number of cases until the power_target is met or the max_value has been reached. Running the function can take a lot of time. Use qp_cases to

Usage

qp_cases_brute(
  power_target,
  start_value = 2,
  max_value = 100,
  progress = TRUE,
  ...
)

Arguments

power_target	Power level target
start_value	Default number of cases for initial search
max_value	Default maximum number of cases for search
progress	Show progress of calculation (default TRUE)
...	qcapower parameters – see qcapower

Value

An integer showing how many cases are needed to achieve the target level of power.
