dojitter: dojitter

Description

This function adds a random uniform vector of the same length as the input to modify the input.

Usage

dojitter(x, amount = 0)

Arguments

x

a vector to be jittered (e.g. a gridpoint vector).

amount

a value of how much to jitter the vector x.

Value

the jittered version of x

Details

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.
