Every model has uncertainties in the variables that it should include.

The Model Averaged Tail Area (MATA) confidence interval has been proposed as a way to deal with model uncertainty. In the Scandinavian Journal of Statistics in 2016, Kabaila, Welsh, and Abeysekara considered the case of two nested linear regression models to assess the performance of MATA confidence intervals.

We extend this study to include the case of three nested linear models.

Additionally, we examine the study conducted by Kabaila & Giri in 2009, where they introduced computationally convenient formulas to compute the confidence interval of two nested linear regression models with uncertain prior information that the simpler model is true. In their computations, they utilized cubic splines.

We aim to improve continuity and computation performance by replacing cubic splines with sinc function interpolations.

Furthermore, we extend this study to the case of three nested linear regression models and derive computationally convenient formulas for the computation of the confidence interval.
