Introduction You have to decide whether a lot of animal feed can be accepted on the basis of one analysis result. You know that the material is non-homogeneous, so that sampling uncertainty should be considered. There is some historical knowledge about the variability of the material: How to ...
Sometimes it may be preferable to construct a confidence interval for logλj. By the delta method, n(logλ^j−logλj)→DN(0,Wjj/λj2). If the population is normal, then the natural logarithm is a variance stabilizing transformation since Wjj/λj2=2, and in such a case, an ...
