МНК для Vb
Есть ли бесплатная библиотека, содержащая средства для аппроксимации массива точек и получения полинома?
Или хотя бы обьясните этот фрагмент из статьи

You can use TREND for polynomial curve fitting by regressing against the same variable raised to different powers. For example, suppose column A contains y-values and column B contains x-values. You can enter x^2 in column C, x^3 in column D, and so on, and then regress columns B through D against column A.
Как это вообще понять???
