In this lecture, we derive the maximum likelihood estimator of the parameter of an exponential distribution. The theory needed to understand the proofs is explained in the introduction to maximum likelihood estimation (MLE). AssumptionsWe observe the first terms of an IID sequence of random ...
In this paper, we propose the approximate maximum likelihood estimator (AMLE) of the scale parameter of the two-parameter exponential distribution for truncated samples. We compare the proposed estimator with the maximum likelihood estimator (MLE) in terms of the mean square error through Monte ...
1. Assuming a 2-parameter exponential distribution, estimate the parameters by hand using the MLE analysis method. 2. Repeat the above using Weibull++. (Enter the data as grouped data to duplicate the results.) 3. Show the Probability plot for the analysis results. ...

The asymptotic distribution of MLE which is univariate normal is used to construct the test. We compare the power of the above test with likelihood ratio test(LRT) given by Gupta, Mehrotra and Michalek(1984) and in the simulated study we observe that for large samples the test based on ...

(8)γ^MLE=n∑i=1nxi. 2.2. Probability Integral Transform Statistic Estimator Assume that x1,x2,…,xn is a random sample from the exponential distribution. Since the CDF of exponential distribution in Eq. (2) is continuous and strictly increasing, the random variables F(x1),F(x2),…,F...
单峰分布(unimodal distribution)& 双峰分布 (bimodal distribution) 数据分布会有一个或者很多个峰值(peaks),数据分布中只有一个明显峰值的叫做单峰,有两个明显峰值的叫做双峰,同样,具有多个峰值的就是多峰。 偏态分布(skewness distribution) 在数据分布的图像展现形式中,偏态分布中一边的观测值要比另一边的观测值多,...
This paper is concerned with the estimation of the Weibull generalized exponential distribution (WGED) parameters based on the adaptive Type-II progressive (ATIIP) censored sample.
