Q: Interpreting Large Coefficients in Logistic Regression

CraigSI am working with a baseball dataset with 30,000 rows, each corresponding to one pitch. The dependent variable is UMP_MISTAKE (binary) with a value of zero meaning the umpire made a correct call and a value of one meaning an incorrect call. Approximately 11% of the values of UMP_MISTAKE are one...

Q: Sorting filenames of a RAR split archive (v3 and v5)

viuserThis simple task of sorting a list of related RAR files of a split archive turned out to be more cumbersome than expected, since there are two versions of the RAR naming scheme, v3 and v5. v3 is like file.rar, file.r00, file.r01 (fixed two digit numbering, except for .rar which is the first part...

Q: Chess jargon(?): "takes" and "castles"

user123444555621Many online chess commentators use phrases like: The best move is takes. I will play castles next. These include an unnecessary third-person s, which sounds incorrect to me. Curiously, this seems to apply only to the verbs take and castle, not to other common chess terms like capture, push, or ...

Q: On the weak convergence of a sequence of probability measures

KrisFor each $E\subset [0,1]$ measurable, I consider the sequence of probability measures $$P_N(E)=\frac{1}{2^N}\sum_{\{J|2J/N\in E\}}^{N/2}\frac{(2J+1)^2}{N+1}\binom{N+1}{N/2+J+1}.$$ Note that $P_N([0,1])=1$ since $2^N=\sum_{J=0}^{N/2}\frac{(2J+1)^2}{N+1}\binom{N+1}{N/2+J+1}.$ The coefficients defin...

Q: Recursive linear orders given by Kleene-Brouwer order

Peter GerdesThe Kleene-Brouwer order $<_{KB}$ transforms a computable tree $T$ on $\omega^{< \omega}$ into a computable linear order (mapping infinite paths through $T$ into infinite descending sequences). What recursive linear orders are isomorphic to the Kleene-Brouwer order on some tree? Define as in [1]...
