# 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
