    Abstract:  The least squares method [1] is a form of mathematical regression analysis that finds the line of best fit for a dataset, providing a visual demonstration of the relationship between the data points. The VSM (Support Vector Machine) method [2] is used to identify Weibull law parameters; and as a consequence, the control of the law of degradation of a good makes it possible to react at the opportune moment. By using the method of least squares, the goal is to find a straight line (D), i.e. to specify the coefficients a and b, such that the sum of the distances “d_i " is minimal, it is ...
