I am using the package OnlineStats (I am open to suggested other packages) to compute the mean, variance, skewness, and kurtosis of data.

The data is Array{Float64,1}.

The following works fine:

mean(data)
var(data)

but skewness and kurtosis throws an error:

skewness(data)
kurtosis(data)

The error I get is:

**MethodError: objects of type Array{Float64,2} are not callable**
**Use square brackets [] for indexing an Array.**
