Proof step
Product of real-rooted factors (elementary)
A fixed real-rooted factor times a proved family factor [1+1], exponent 1 n + 1
- Concludes
- Triangle read by rows: T(n,k), for k=-n..n-1, is the scaled (by 2^n n!) probability that the sum of n uniform [-1, 1] variables is between k and k+1.
- Premises
- row_factor parent of Triangle read by rows: T(n,k), for k=-n..n-1, is the scaled (by 2^n n!) probability that the sum of n uniform [-1, 1] …
sequence: Every row P_n, n >= 0, is zero or real-rooted with all roots in (-inf, 0]
