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. 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. WebA small sample will give a deceptively large R-squared. Ping Yin & Xitao Fan, J. of Experimental Education 69(2): 203-224, "Estimating R-squared shrinkage in multiple regression", compares different methods for adjusting r-squared and concludes that the commonly-used ones quoted above are not good.

WebAug 4, 2024 · Introduction. Hotelling's T 2 (T-Squared), Q residuals, and their corresponding contributions, are summary statistics which help explain how well a model is describing a given sample, and why that sample has its observed scores in a given model. The statistics are described for factor-based models like Principal Components Analysis and ...
