dispersion,RepeatedRanking: Compute genewise dispersion measures for repeated rankings

Description Usage Arguments Value Author(s) See Also

Dispersion is computed with respect to ranks, computed genewise. Three different measures are implemented: standard deviation (sd), median absolute deviation (mad), and interquartile range (IQR). The function is primarily intended to serve as helper function for AggregatePenalty.

1	dispersion(RR, measure = c("sd", "mad", "iqr"), scheme = c("original", "symmetric", "user"), center = NULL)

`RR`	An object of class `RepeatedRanking`.
`measure`	Specifies the dispersion measure, s. description.
`scheme`	Specifies how the location parameter is computed. If `scheme="original"`, then the location parameter is chosen as the reference ranking (slot `original`). If `scheme = "symmetric"`, then `original@ranking` and `rankings` are pooled to compute the location parameter either as the joint mean (if `measure` = "mean") or the joint median (if `measure = "median"`). Alternatively, the user may provide locations by using the `center` argument.
`center`	Location parameters to be used. Used only if `scheme` = "user".
