PHI Function Explained
The PHI function in Microsoft Excel calculates the value of the phi (or φ) function, which is the cumulative distribution function of the standard normal distribution. It takes a single argument, x, which is a value between -1 and 1, and returns the probability that a random variable with a standard normal distribution is less than or equal to x.
