Arguments
data |
Data of a univariate distribution for which the test statistic is computed (vector) |
alpha |
The two-sided decision threshold used for hypothesis-testing |
j |
The # hypotheses tested; used to compute a Bonferonni correction, if applicable; should remain at its default if multiple testing is not an issue (scalar) |

Value
An object including the test statistic, p-value, and a significance flag (list)
