updated readme re 'valid' codes

parent 565aca36
......@@ -16,6 +16,6 @@ Notes (mostly to self):
* UPRN = unique property reference = linkage mechanism (uses AddressBase)
Issues:
* Gcons<year>valid variable has undefined labels: G, L, M = ? 0 = off gas & V = valid reading (range 0 - 50,000) so presumably L = large (> 50,000?) and M = missing? But G?
* <fuel>cons<year>valid variable has undefined labels: G, L, M = ? 0 = off gas/elec & V = valid reading (gas range 0 - 50,000; elec range = 100 - 25,000) so presumably L = large (> 50k or 25k depending?) and M = missing? But G?
* ideally DECC should set missing to -99 to aid re-coding and avoid unpleasant surprises in naive analysis!
