WebThe Wikipedia entry on them has a picture of what you're actually summing (finding the number of balls in a square bottomed pyramid), so maybe you can see why they aren't as easy to sum as the triangular numbers, which can easily be arranged into squares. The MathOverflow link by aelguindy gives a "visual proof" of how the formula is derived. WebCalculating a t score is really just a conversion from a z score to a t score, much like converting Celsius to Fahrenheit.The formula to convert a z score to a t score is: T = (Z x 10) + 50. Example question: A candidate for a job takes a written test where the average score is 1026 and the standard deviation is 209. The candidate scores 1100.

WebSome heuristics are that the "singular support" of a distribution controls what it can be multiplied by in a naive sense (distributions with a disjoint singular support). So squaring the delta function is the first bad case - whatever the singular support means, it must be the set containing 0 for the delta function.
