dojitter {adlift} | R Documentation |
This function adds a random uniform vector of the same length as the input to modify the input.
dojitter(x, amount = 0)
x |
a vector to be jittered (e.g. a gridpoint vector). |
amount |
a value of how much to jitter the vector x . |
The function creates length(x)
samples from a uniform[-amount
,amount
], and adds these to the original vector x
. If amount=0
, the new vector jx
is the same as the original vector.
jx |
the jittered version of x |
