The random generation should fall under normal or poisson distribution.
I have been trying to generate a set of 100 new numbers from previous 10 numbers. The new numbers generated must fall near 2 to 3 deviations from the mean. The problem is that when I have negative numbers, the random function gives me NaN number. It is important for me to keep those negative numbers for the generation since they are a result of a previous calculation in the code. Do we have another way to go about this? All suggestions are highly appreciated. Thanks in advance

Which "random function" are you talking about?
In a new comment, please show us the exact code that you tried.

Hi, X = rand returns a single uniformly distributed random number in the interval (0,1). Then you can multiply it and add constants.
For example, X = rand*2 -1; will return random number between (-1,1).
