Do you mean that you want to multiply each value in the dataset by a random number between 1.005 and 1.02, with all random numbers equally likely in that range? This could be done with something like:
multiplier = 1.005 + rand(size(values))*(1.02-1.005);
values = values *. multiplier;

@Stephen john Sorry I am not following you. Maybe you could give a few numerical examples?
