The probability of getting values very far from the mean is larger with a t-distribution than a normal distribution. Normal vs. t-distribution. Limitations of Using a T-Distribution ...

A normal distribution, for instance, is depicted by a bell-shaped curve with an uninterrupted line covering all values across its probability function. What Is a Discrete Probability Model?

Properties of P-P and Q-Q probability plots for visually assessing the fit of probability models are reviewed. It is shown how to construct families of curves for standardized P-P plots, which are ...
