Abadir K M, Heijmans R, Magnus JR, Statistics (2018, Table of Contentschapter abstracts, corrections & additions), Cambridge University Press, Volume 2 in the series  Econometric Exercises. The corrections & additions for Volume 1, Abadir and Magnus (2005), Matrix Algebra, is given here.

The erratum for 3 papers on unit roots in the 1990s is given here.

The 99.5% quantiles from Theorem 1 of Abadir and Paruolo (1997) are 10.06 for Zu and 7.836 for Zr, which extends the results in Table I. These may be used for 2-sided inference at the 1% level. 

Download the R code for calculating the Kummer 1F1 function as in Abadir (1999). In connection with this paper, see also: Abadir KM (2002).

The files of Abadir and Magnus (2002) (incl. PDF paper, LaTeX paper, LaTeX style file ee.sty) are downloadable here. If you're a user of SW(P), you can input the ee.sty file in your "preamble" (\input{ee.sty}), and access the LaTeX commands by downloading this SW(P)5 reg file and copying AR.0261-AR.0428 into your own reg file; see this sample file. Alternatively (not as convenient), try this SW(P)3.5 shell file. Finally, there is also the CTAN package written by Erik Kole.

We are grateful to Professors João Pedro Nunes and João Pedro Ruas for pointing out an error in (A.8) of Abadir and Rockinger (2003). It occurs in the simplification of (A.7) to (A.8): the former is correct but the latter should be c₁=m₂-m₁+c₂(m₂-2m₁). The simplified c₁ of the uncorrected (A.8), as stated also in (16) in our paper, restricts the centring of both components of the RND to be the same (i.e., m₁= m₂), which is not necessary unless supported by the data. This restriction would have reduced our R2 compared to using the corrected (A.8). In general, we recommend that users implement (A.7) unless their estimated parameters fit a restriction that reduces (A.7) to the corrected (A.8).
