           three covariates (V1, V2, V3) the value of Tvaraff[j], but in fact
         * Makefile: Summary: 0.99r16          the equation model is restricted to two variables only (V2, V3)
           and the combination for V2 should be codtabm(k,1) instead of

           codtabm(k,TnsdVar[Tvaraff[j]]. Many many changes have been
         * imach.c: Summary: Some bugs fixed          made. All of these should be simplified once a day like we did in
           hpxij() for example by using precov[nres] which is computed in
 2018-05-02  Brouard Nicolas  <brouard@ined.fr>          decoderesult for each nres of each resultline. Loop should be done
           on the equation model globally by distinguishing only product with
         * imach.c:  Summary: Bug for young ages (<-30) will be in r17          age (which are changing with age) and no more on type of
