Imputation and derivation

Derivation

variable: waiscf [first waist result] (table[s]: ncdk_persexam & ncdl_persexam)
variable: waiscs [second waist result] (table[s]: ncdk_persexam & ncdl_persexam)
Missing values removed and an average of the 2 (waiscf, waiscs) measurements calculated; if only one measurement was taken that is used.
replace waiscf=. if waiscf==999
replace waiscs=. if waiscs==999
replace waiscf=waiscs if waiscf==.
replace waiscs=waiscf if waiscs==.
gen waist=(waiscf+waiscs)/2
