WebJan 19, 2016 · Sorted by: 1. Use the rand () function with the 'exponential' argument; however, if you want between 9% and 14% of the values to be < 1, you'll need to solve for Lambda using the formula for the CDF of the exponential distribution. Personally, just to save time, I would simulate some values of Lambda and select the one that fits the criteria.
