x |
A numeric vector. |
probs |
Error probabilites. The default c(0.025, 0.975) gives a symmetric 95% confidence interval. |
constant |
Scaling factor applied. The default (1.4826) ensures that the MAD equals the standard deviation for a theoretical normal distribution. |
type |
Type of confidence interval. Currently not used as the only type is "bootstrap". |
boot_type |
Type of bootstrap confidence interval c("bca", "perc", "norm", "basic"). |
R |
The number of bootstrap resamples. |
seed |
An integer random seed. |

Further arguments passed to |
Bootstrap confidence intervals are calculated by the package "boot", see references. The default bootstrap type is "bca" (bias-corrected accelerated) as it enjoys the property of being second order accurate as well as transformation respecting (see Efron, p. 188).
