    Sainmhíniú transformation of a variable x to a new variable y by some such relation as y = a + b log(x-c) Tagairt Kendall & Buckland, Dictionary of Statistical Terms, 1982
    Nóta There are a number of contexts in which such transformations are useful in statistics, e.g. to normalise a frequency function, to stabilise a variance, and to reduce a curvilinear to a linear relationship in regression or probit analysis.
