Disentangling the impact of mean reversion in estimating policy response with dynamic panels
Dependence Modeling, 2022 This article accounts for multivariate dependence of the variable of policy interest in dynamic panel data models by disentangling the two sources of intertemporal dependence: one from the effect of the policy variable and the other from mean reversion ...

Geometric View of Measurement Errors [PDF]
, 2010 The slope of the best fit line from minimizing the sum of the squared oblique errors is the root of a polynomial of degree four. This geometric view of measurement errors is used to give insight into the performance of various slope estimators for the ...

Validating linear restrictions in linear regression models with general error structure [PDF]
, 2006 A new method for testing linear restrictions in linear regression models is suggested. It allows to validate the linear restriction, up to a specified approximation error and with a specified error probability.

Quotient of information matrices in comparison of linear experiments for quadratic estimation
Open Mathematics, 2017 The ordering of normal linear experiments with respect to quadratic estimation, introduced by Stępniak in [Ann. Inst. Statist. Math. A 49 (1997), 569-584], is extended here to the experiments involving the nuisance parameters. Typical experiments of this

Computational and Mathematical Methods in Medicine, Volume 7, Issue 1, Page 45-51, 2006., 2006 Meta‐analysis is a widely used tool to synthesize the results of a set of primary studies leading to more powerful conclusions than those provided by isolated ones. To evaluate the effect of allocated radiotherapy, types of breast surgery and other risk factors over death risk in early breast cancer patients, we carried out a meta‐analysis using ...

Open Mathematics, 2020 In this article, an errors-in-variables regression model in which the errors are negatively superadditive dependent (NSD) random variables is studied. First, the Marcinkiewicz-type strong law of large numbers for NSD random variables is established. Then,

Testing the stability of regression parameters when some additional data sets are available
International Journal of Mathematics and Mathematical Sciences, Volume 17, Issue 1, Page 173-180, 1994., 1992 We consider the problem of testing the stability of regression parameters in regression lines of different populations when some additional, but unidentified, data sets from those populations are available. The standard test (T0) discards the additional data and tests the stability of the regression parameters using only the data sets from identified ...

The effect of a single point on correlation and slope
International Journal of Mathematics and Mathematical Sciences, Volume 13, Issue 4, Page 799-805, 1990., 1990 By augmenting a bivariate data set with one point, the correlation coefficient and/or the slope of the regression line can be changed to any prescribed values. For the target value of the correlation coefficient or the slope, the coordinates of the new point are found as a function of certain statistics of the original data.
