areanormal

areanormal

Value assigned to an area taken from a normal distribution

Result = areanormal(areaclass)
areaclass
spatial boolean,nominal,ordinal
Result
spatial scalar

Operation

The area to which a cell belongs is identified by areaclass: cells with corresponding values on areaclass are member of a separate area. The Result is generated with a random number generator: for each area on areaclass, a random number is taken from a normal distribution with mean 0 and standard deviation 1. This value is assigned to all cells belonging to that area.

Notes

A cell with a missing value on areaclass is assigned a missing value on Result.

Group

This operation belongs to the group of Random number generators; Areas

Examples

  1. • pcrcalc
    binding
    Result = Result.map;
    Class = Class.map;
    initial
    report Result = areanormal( Class);

    • python
    Class = readmap(“Class.map”)
    Result = areanormal( Class)
    Result.map Class.map
