moment {e1071} | R Documentation |
Computes the (optionally centered and/or absolute) moment of order
order
. When center
and absolute
are both
FALSE
, the moment is simply sum(x ^ order) / length(x)
.
moment(x, order=1, center=FALSE, absolute=FALSE, na.rm=FALSE)
x |
a numeric vector containing the values whose moment is to be computed. |
order |
order of the moment to be computed, the default is to compute the first moment, i.e., the mean. |
center |
a logical value indicating wether centered moments are to be computed. |
absolute |
a logical value indicating wether absolute moments are to be computed. |
na.rm |
a logical value indicating whether NA values
should be stripped before the computation proceeds. |

x <- rnorm(100) # Compute mean and variance moment(x) moment(x, order=2, center=TRUE) # Compute the 3rd absolute centered moment moment(x, order=3, center=TRUE, absolute=TRUE)
