WebMay 19, 2024 · The Cumulative Density Function (CDF) is simply the probability of the random variable, x, falling at or below a given value. For example, this type of function would be used if you wanted to know the probability of your temperature sensor noise being less than or equal to 5 Hz. The CDF for a normal distribution is described using the …
