+
+	* imach.c: With products of covariates (age or dummies or
+	quantitatives), estimates of parameters were good but when
+	estimating variances the positions of newly created covariates
+	were wrongly assigned and results were wrong. Thank to Feinua_Sun!

+
+	* imach.c (Module): Some attempts to find a bug of wrong estimates
+	of confidencce intervals with product in the equation modelC

+
+	* imach.c (Module): Fixed covariates (dummy or quantitative)
+	with missing values have never been allowed but are ERRORS and
+	program quits. Standard deviations of fixed covariates were
+	wrongly computed. Mean and standard deviations of time varying
+	covariates are still not computed.

 	* 99r25 Improvements in fixing discrepancies between covariates
 	missing in result line but in model.
