Outline of Final Research Achievements |
We have developed algorithms for finding the confidence region for specifying the confidence level that trusts the location estimates by constructing the statistical model and estimating its parameters of the position estimation of the person in the room with high precision. It is possible to accurately estimate the location parameter by the rotation distributions from the Weibull distribution and the lognormal distribution which are positive distributions. By using the implicit function theorem, we can calculate the asymptotic distribution of the conditional maximum likelihood estimators for confidence regions of the location.
