Chi square and exponential distribution
WebDec 6, 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 $1-2\lambda$. Web“observed” values to test the GoF follows a Chi-Square distribu-tion. Hence, the name Chi-Square test. In what follows we proceed as in Figure 1, using several data sets to fit a Normal, an Exponential, and a Weibull distribution. We will work with the same data sets used in the STARTsheets that discussed these empirical GoF procedures [7 ...

WebSep 14, 2015 · As the chi-square is a special case of the gamma distribution with shape $\alpha=k/2$ and rate $\beta=1/2$, I initially tried using this. However I end up with $\theta=-1/k$ and $\phi=2/k$. In other words, the top and bottom of the first term in the exponential pdf form are literally just multiplied by $1/k$ in order to force a canonical ...
