Interview with Søren Johansen and Sebastian Skovsted of Johansen Skovsted Arkitekter

Johansen 1..13

Currently, no approved therapeutics exist to treat or prevent infections induced by Ebola viruses, and recent events have demonstrated an urgent need for rapid discovery of new treatments. Repurposing approved drugs for emerging infections remains a critical resource for potential antiviral therapies. We tested ~2600 approved drugs and molecular probes in an in vitro infection assay using the t...

The Wold Representation, Cointegration and the Johansen Trace Test +,*

This paper considers the importance of moving average errors for the Johansen trace test of cointegrating rank based upon approximating vector autoregressions (VARs). Two cases are emphasized and explored, both taking as their starting point the Wold decomposition. Though each case defined satisfies the same cointegrating vector, one is a case of multicointegration while the other, based on res...

Using audit to improve senior house officer training Antony Johansen

Accepted 6 May 1997 Summary The British Geriatrics Society has described 16 training objectives for senior house officers (SHOs) in geriatric medicine. We have developed these into an audit standard, and in a controlled trial we consider the effectiveness of audit as a means of monitoring and improving SHO training. SHOs from three hospitals were sent a questionnaire asking about the adequacy o...

Likelihood inference for a vector autoregressive model which allows for fractional and cofractional processes ∗ ( Version 20 ) Søren Johansen † University of Copenhagen and CREATES and Morten

This paper discusses model based inference in a vector autoregressive model for cofractional processes based on the Gaussian likelihood. The model allows the process Xt to be fractional of order d and cofractional of order d−b, that is, there exist vectors β for which βXt is fractional of order d − b. The parameters b and d satisfy either d ≥ b ≥ 1/2, d = b ≥ 1/2, or d = d0 ≥ b ≥ 1/2. We model ...
