Substantiation of specification of regressional dependences in tasks of value evaluation

The author considers the problems of constructing regression dependencies for the purposes of cost estimation. Since often deviations of prices from such dependencies have a distribution different from the normal one, the well-known robust methods allow this to be taken into account, but do not allow one to choose the best type of regression dependence, having heavier tails. Examples of the application of this method to the assessment of machinery, equipment and buildings are given.
