Change Point Estimation of a Process Variance with a Linear Trend Disturbance
When a change occurs in a process, one expects to receive a signal from a control chart as quickly as possible. Upon the receipt of signal from the control chart a search for identifying the source of disturbance begins. However, searching for assignable cause around the signal time, due to the fact that the disturbance may have manifested itself into the rocess sometimes back, may not always l...
متن کاملEstimating Fishing Mortality, Natural Mortality, and Selectivity Using Recoveries from Tagging Young Fish
—Current methods for estimation of ageand year-specific instantaneous mortality rates based on multiyear, multiple-age tagging studies assume that it is feasible to tag fish in a wide range of ages. For some species, however, only the youngest one or two age-classes are readily available for tagging. Given the practical advantages of tagging young fish only, an important question is whether suc...
متن کاملEstimation of Absolute and Relative Survival Rates from the Recoveries of Dead Animals
Circumstances that give rise to samples of dead animals from natural populations are considered and five important particular situations are emphasized. In two of these situations it is possible to estimate the absolute mortality rates of animals in the natural populations concerned. In the other three situations the populations comprise two or more different types of animal and only the relati...
متن کاملOptimal Change-Point Estimation from Indirect Observations
We study nonparametric change-point estimation from indirect noisy observations. Focusing on the white noise convolution model, we consider two classes of functions that are smooth apart from the change-point. We establish lower bounds on the minimax risk in estimating the change-point and develop rate optimal estimation procedures. The results demonstrate that the best achievable rates of conv...
