About one interpolation problem

Abstract

In questions related to the approximate definition of a function, one encounters the problem of constructing an approximate expression of a function by its mean values given for a number of intervals. An example of this may be drawing the equation of a distribution curve or drawing the equation of a regression line of one of two random variables on the other. To the same problem is given the finding of the distribution of a mineral in a well on the basis of readings obtained from core analyses, and a number of other sampling questions.
