nise {sm} | R Documentation |
This function evaluates the integrated squared error between a density
estimate constructed from a standardised version of the univariate data
y
and a standard normal density function.

y |
a vector of data. |

The data y
are first standardised to have sample mean 0 and sample
variance 1. The integrated squared error between a density estimate
constructed from these standardised data and a standard normal distribution
is then evaluated.
