Abstract:

The role of an ancillary statistic as an information and as a precision index is discussed. For transformation models, it can be shown that, in some sense, two samples with the same ancillary statistic value contain the same amount of information. For both transformation and exponential models, the variance of the conditional Fisher information is proportional to the square of the statistical curvature. It appears that the constancy of statistical curvature is related to the concept of exact precision index. Author
