Bootstrapping with a progress bar
boot_estimate_valid( reps, x, nom.rate, id.rate, pop.mean = 0, pop.sd = 1, adjust = 1 )
reps |
Number of bootstrapped repetitions. |
x |
Numeric vector of observed scores. |
nom.rate |
Nomination rate. Must be between 0 and 1. |
id.rate |
Identification rate. Must be between 0 and 1. |
pop.mean |
The known general population mean of x. Defaults to 0. |
pop.sd |
The known general population standard deviation of x. Defaults to 1. |
adjust |
Controls the bandwidth of the density estimator. Defaults to 1.0, which has been found to perform well in simulation. |
