WebbIn mathematics, the method of equating the coefficients is a way of solving a functional equation of two expressions such as polynomials for a number of unknown parameters. … Webb3 apr. 2024 · Variable x represents the input information provided to the model at any given time. p0 = y-axis intercept (or the bias term). p1 = the regression coefficient or scale factor. In classical statistics, p1 is the equivalent of the slope of the best-fit straight line of the linear regression model. pi = weights (in general).
