Rectangular Confidence Regions and Prediction Regions in Multivariate Calibration

نویسندگان

چکیده

The multivariate calibration problem deals with inference concerning an unknown value of a covariate vector based on observation response vector. Two distinct scenarios are considered in the problem: controlled where covariates non-stochastic, and random random. Under calibration, interest is computation confidence region for that computing prediction Assuming standard normal linear regression model, rectangular regions derived using parametric bootstrap approach. Numerical results show accurately maintain coverage probabilities. illustrated examples. currently available literature all ellipsoidal, this work first attempt to derive regions.

Joint Confidence Regions

Confidence intervals are one of the most important topics in mathematical statistics which are related to statistical hypothesis tests. In a confidence interval, the aim is that to find a random interval that coverage the unknown parameter with high probability. Confidence intervals and its different forms have been extensively discussed in standard statistical books. Since the most of stati...

Bootstrap prediction regions for multivariate autoregressive processes

Riassunto: L’obiettivo del presente lavoro è studiare il comportamento di una nuova procedura per la determinazione di regioni di previsione per processi autoregressivi multidimensionali. Le regioni di previsione, basate sulla tecnica bootstrap, non fanno affidamento su alcuna assunzione distributiva per i disturbi ed inoltre tengono conto della variabilità derivante dalla necessità di stimare ...

Minimum Volume Confidence Regions for a Multivariate Normal Mean Vector

Since Stein’s original proposal in 1962, a series of papers have constructed confidence regions of smaller volume than the standard spheres for the mean vector of a multivariate normal distribution. A general approach to this problem is developed here, and used to calculate a lower bound on the attainable volume. Bayes and fiducial methods are involved in the calculation. Scheffe-type problems ...

Rayleigh Confidence Regions based on Record Data

This paper presents exact joint confidence regions for the parameters of the Rayleigh distribution based on record data. By providing some appropriate pivotal quantities, we construct several joint confidence regions for the Rayleigh parameters. These joint confidence regions are useful for constructing confidence regions for functions of the unknown parameters. Applications of the joint confid...

Confidence Regions for Barcodes

The results of [3] suggest a way to sort which barcode intervals correctly belong to the underlying manifold, M , and which can be regarded as topological noise. In particular, when barcodes are computed using sublevel sets of their distance function (see eq 12), all of the barcodes that start later than a linear function of W2(F̂n, F ) can be assumed to correctly reflect the betti numbers of M ...
