the bits that were gone back right here okay so there are two sort of two points that we should talk about when when getting B ba and s working with continuously variable models like via East which is that disease these are continuous so Z is comes from a standard normal distribution and so we can't really cope continuous data but what we can do is district ice it to some high precision and so if you take Z and you discretize it to some level Delta Z then you pretty much turned a probability density function by P of Z and you turn
