+***     Consolidated Approach for Reporting Indicators of Food Security (CARI)
+***                 CALCULATE CARI using FCS, rCSI, LCS and ECMEN
+
+*** ----------------------------------------------------------------------------------------------------------------*
+
+*Note that there are two ways to calculate CARI - using ECMEN or FES. This syntax file is for calculating CARI using ECMEN (version excluding assistance). However, please navigate to the script for CARI using FES as relevant. 
+* Guidance on CARI can be found here: https://www.wfp.org/publications/consolidated-approach-reporting-indicators-food-security-cari-guidelines.
+
+*Note: this syntax file is based on the assumption that the scripts of the various indicators that compose this version of the CARI (FCS, rCSI, LCS-FS, ECMEN)  have already been run. 
+* You can find these scripts here: https://github.com/WFP-VAM/RAMResourcesScripts/tree/main/Indicators.
+*The following variables should have been defined before running this file:
+                FCSCat21 and/or FCSCat28 
+                rCSI
+                Max_coping_behaviourFS	
+                ECMEN_exclAsst 
+                ECMEN_exclAsst_SMEB.		
+
+*-------------------------------------------------------------------------------*
+* Process FCS for CARI computation
+*-------------------------------------------------------------------------------*
+
+* Important note: pay attention to the threshold used by your CO when selecting the syntax (FCSCat21 or FCSCat28). In this example, the 21-35 treshold is used.  
+    
+ *** Create FCS_4pt for CARI calculation.
+Recode FCSCat21 (1=4) (2=3) (3=1) INTO FCS_4pt. 
+Variable labels FCS_4pt '4pt FCG'.
+Value labels FCS_4pt 1.00 'Acceptable' 3.00 'Borderline' 4.00 'Poor'. 
+EXECUTE.
+
+*-------------------------------------------------------------------------------*
+* Combine rCSI with FCS_4pt for CARI calculation (current consumption) 
+*-------------------------------------------------------------------------------*
+
+Do if (rCSI  >= 4).
+Recode FCS_4pt (1=2).
+End if.
+EXECUTE.
+
+Value labels FCS_4pt 1.00 'Acceptable' 2.00 ' Acceptable and rCSI>4' 3.00 'Borderline' 4.00 'Poor'. 
+EXECUTE.
+
+*-------------------------------------------------------------------------------*
+* Process ECMEN for CARI computation
+*-------------------------------------------------------------------------------*
+
+***Recode ECMEN. 
+IF (ECMEN_exclAsst=1) ECMEN_MEB=1. 
+IF (ECMEN_exclAsst=0 & ECMEN_exclAsst_SMEB=1) ECMEN_MEB=2. 
+IF (ECMEN_exclAsst=0 & ECMEN_exclAsst_SMEB=0) ECMEN_MEB=3.
+
+***Recode the `ECMEN_MEB' variable into a 4pt scale for CARI console.
+Recode ECMEN_MEB (1=1) (2=3) (3=4) INTO ECMEN_class_4pt. 
+Variable labels ECMEN_class_4pt 'ECMEN 4pt'.
+EXECUTE.
+ 
+Value labels ECMEN_class_4pt 1.00 'Least vulnerable' 3.00 'Vulnerable' 4.00 'Highly vulnerable'. 
+EXECUTE.

+Compute Mean_coping_capacity_ECMEN = MEAN (Max_coping_behaviourFS, ECMEN_class_4pt).  
+Compute CARI_unrounded_ECMEN = MEAN (FCS_4pt, Mean_coping_capacity_ECMEN). 
+Compute CARI_ECMEN = RND (CARI_unrounded_ECMEN).  
+Variable labels CARI_ECMEN 'CARI classification (using ECMEN)'.
+EXECUTE. 
+
+Value labels CARI_ECMEN 1 'Food secure'   2 'Marginally food secure'   3 'Moderately food insecure'   4 'Severely food insecure'.
+EXECUTE.
