 Description: Motivated by changing administrative boundaries over time,
     the 'nuts' package can convert European regional data with NUTS codes
     between versions (2006, 2010, 2013, 2016 and 2021) and levels (NUTS 1,
-    NUTS 2 and NUTS 3). The package uses spatial interpolation based on
-    granular (100m x 100m) population and land use data provided by the
-    European Commission's Joint Research Center.
+    NUTS 2 and NUTS 3). The package uses spatial interpolation as in Lam
+    (1983) <doi:10.1559/152304083783914958> based on granular (100m x
+    100m) area, population and land use data provided by the European
+    Commission's Joint Research Center.
