摘要
在双参数指数分布的两个参数的区间估计的基础上,利用Lagrange乘子法和函数单调性得到了各参数的最短置信区间的唯一存在性,给出了各参数最短置信区间的表达式及其等距搜索算法.
Based on the estimation of the interval of the parameters on two-parameter exponential distribution, the unique existence of the shortest confidence interval on each parameter was derived , by using the Lagrange multiplier method and the monotonicity of functions. Furthermore, the formula of the shortest confidence interval was derived by using equidistant search method.
