Description
Computes the kurtosis of a given vector.
Usage
1
ds.kurtosis(x = NULL, datasources = NULL)
Arguments
x
a character, the name of a numerical vector
datasources
a list of opal object(s) obtained after login in to opal servers;
these objects hold also the data assign to R, as data frame, from opal datasources.
Details
Considering x[i] for elements of x and x* for their mean, so m[r] = ∑[i](x[i]-x*)^r/n
is the sample moments of order r.
Which ∑[i](x[i]-x*)^r is computed at each data node and combined by this function in the central node, also called client-side.
It is a wrapper for the server side function getKurtosis.
Value
return a numeric value.
Dependencies
getKurtosis, ds.arMean, ds.length
