Probability greater than chi square
Webb6 dec. 2024 · Everything being positive, we may as well square and reorganize: $$ e^{-2\lambda-4\lambda^2} \leq 1 - 2\lambda $$ Then it should be obvious why the inequality holds on some neighborhood of $0$: the RHS is $1-2\lambda-2\lambda^2 + o(\lambda^2)$ around 0, so for $\lambda$ small enough is less than $1-2\lambda$. http://physics.ucsc.edu/~drip/133/ch4.pdf
