Arnold has what he calls "water on the brain", which would correctly be referred to as hydrocephalus. Crandall points out that Arnold is never held back by his disability, but in fact laughs at himself: "With my big feet and pencil body, I looked like a capital L walking down the road." According to Crandall, the illustrations by Ellen Forney, which are meant to be the cartoons that Arnold draws, represent a new way for the disabled narrator to communicate with the readers: they "initiate further interpretations and
Sum of normally distributed random variables distribution are obvious by comparison with the standard normal distribution. Sum of normally distributed random variables In probability theory, calculation of the sum of normally distributed random variables is an instance of the arithmetic of random variables, which can be quite complex based on the probability distributions of the random variables involved and their relationships. This is not to be confused with the sum of normal distributions which forms a mixture distribution. If "X" and "Y" are independent random variables that are normally distributed (and therefore also jointly so), then their sum is also normally distributed. i.e., if then This
