The kurtosis is one of the central moments of a distribution by means of which the curve is defined. A kurtosis with value 0 is mesokurtic, a kurtosis with a value greater than 0 is leptokurtic and a kurtosis with a value less than 0 is platykurtic.

Note: Often, the terms excess and kurtosis are used interchangeably, when in fact the excess refers to the kurtosis coefficient.
