The Smearing retransformation is used in regression analysis, after estimating the logarithm of a variable. Estimating the logarithm of a variable instead of the variable itself is a common technique to more closely approximate normality. In order to retransform the variable back to level from log, the Smearing retransformation is used.

If the log-transformed variable y is estimated as:

log(y)=f(X)+er

then, the level variable is given by:

y=exp(f(X))exp(er). I am Chester from Den Haag. I am learning to play the Cello. Other hobbies are Running.
