-The function `qp_cases_brute()` allows you to estimate how many cases you need to achieve a target level of power. The function input comprises all specifications of `power_target` (the intended level of power) and all parameters except `cases`. The function runs simulations and iteratively searches for the number of cases yielding a power estimate that is sufficiently close to the target level. (see above on the closeness of the target level and the estimated level).
+The function `qp_cases_brute()` allows you to estimate how many cases you need to achieve a target level of power. The function input requires the desired level of power (`power_target`) and all parameters known from `qcapower()` except `cases`. The function runs simulations and iteratively searches for the number of cases yielding a power estimate that is sufficiently close to the target level. (see above on the closeness of the target level and the estimated level).
 
 **Note:** Running the function may take some time with a high number of simulations and permutations.
