alloc.simple {BATSS} | R Documentation |
Simple allocation function
Description
alloc.simple independently randomises each unit to a group (i.e., flips a coin for each unit) so that the observed allocation probabilities may be far from the target ones. This strategy is often considered to be a poor choice.
Usage
alloc.simple(m, prob)
Arguments
m |
the 'BATSS' ingredient ' |
prob |
the 'BATSS' ingredient ' |
Value
alloc.simple returns an object of class factor of length 'm
' with levels matching the names of the vector 'prob
'.
See Also
alloc.balanced()
, another group allocation function.
Examples
alloc.simple(100, prob = c(A=.4,B=.6))
table(alloc.simple(100, prob = c(A=.4,B=.6)))
table(alloc.simple(100, prob = c(A=.4,B=.6)))
