On a test of equality of scale parameters of several exponential distributions
TLDR
The null distribution of the likelihood ratio criterion for testing the quality of scale parameters of p(p>2) two parameter exponential distributions for the case of equal sample sizes is obtained in a closed form for the first time as discussed by the authors.Abstract:
In this paper, null distribution of the likelihood ratio criterion for testing the quality of scale parameters of p(p>2) two parameter exponential distributions for the case of equal sample sizes is obtained in a closed form for the first time. A short table of the critical values of the test statistic is also presented.read more

Comparing scale parameters in several gamma distributions with known shapes
Ali Akbar Jafari,Javad Shaabani +1 more
TL;DR: Eleven approaches for testing the equality of scale parameters in gamma distributions when shape parameters are known are presented, applicable to other problems such as testing homogeneity of variances in normal distributions, verifying equality of Scale-like parameters in inverse Gaussian distributions, and comparing scale parameter values in two-parameter exponential distributions with censored data or K-record values.
