         *  (Module): imach.c Update mle=-3 (for computing Life expectancy          * r29 W and not sqrt(Wald)
         and life table from the data without any state)  
   2022-07-22  Nicolas Brouard   <brouard@ined.fr>
 2019-05-20  Brouard Nicolas  <brouard@brouard.name>

   2022-05-30  Brouard Nicolas  <brouard@brouard.name>
         * imach.c: Summary: Projection syntax simplified  
         We can now start projections, forward or backward, from the mean date          * imach.c: With products of covariates (age or dummies or
         of inteviews up to or down to a number of years of projection:          quantitatives), estimates of parameters were good but when
         prevforecast=1 yearsfproj=15.3 mobil_average=0          estimating variances the positions of newly created covariates
         or          were wrongly assigned and results were wrong. Thank to Feinua_Sun!
         prevforecast=1 starting-proj-date=1/1/2007 final-proj-date=12/31/2017 mobil_average=0  
         or  2022-05-24  Nicolas Brouard   <brouard@ined.fr>

         prevbackcast=1 starting-back-date=1/10/1999 final-back-date=1/1/1985 mobil_average=1          of confidencce intervals with product in the equation modelC
