Scale-Up and Masking (with 4 questions = 2 above + 2 extra)
Definitions
For a given NAME:
t = "total number of alters named NAME that the respondent knows"
k = "has name NAME and knows respondent uses drugs"
u = "has name NAME and respondent knows he uses drugs"
xy = x and y
~z = not z
- Example
- ~k~u: alters who do not use drugs and have no knowledge of the respondent's use
Equations
ku + k~u + ~ku + ~k~u = t
ku + k~u = k
~ku + ~k~u = ~k
ku + ~ku = u
k~u + ~k~u = ~u
Questions
?t = T
?k = K
?u = U
?ku = KU
Examples
~k~u = ~u - k~u = t - u + ku - k = T - K - U + KU
k~u/~u = (k - ku) / (t - u) = (K - KU) / (T - U)
