# Class "SpatialCumulativeDistributionFunction"

### Description

The spatial cumulative distribution function (SCDF) is estimated by applying Equation 7.13 in de Gruijter et al., (2006) to indicator transformations of the data. See also page 83 of de Gruijter et al., (2006).

### Objects from the Class
