I need help with another problem I am having that deals with the generation of vectors that I asked about yesterday.  I now need to have each value in the vector (all values either 1 or -1) have a probability p that it will switch signs (so, say, each value has a 50% chance of switching from -1 to 1 or visa versa).  What would be the best way to go about doing this?  Thank-you!!
