indivRisk {sdcMicro} | R Documentation |
Base individual risk computation.
indivRisk(x, method = "approx", qual = 1, survey=TRUE)
x |
object from class freqCalc |
method |
approx (default) or exact |
qual |
final correction factor |
survey |
TRUE, if one have survey data and FALSE if one deal with the whole population. |
Determines the risk for each observation. After the risk is computed one can use e.g. the function localSuppr() for the protection of values of high risk. Further details can be found at the link given below.

fk |

The base individual risk method was developed by Benedetti, Capobianchi and Franconi

## example from Capobianchi, Polettini and Lucarelli: data(francdat) f <- freqCalc(francdat, keyVars=c(2,4,5,6),w=8) f f$fk f$Fk ## individual risk calculation: indivf <- indivRisk(f) indivf$rk
