find the values of the parameters (β0, β1, …, βn) that minimize the sum of the squared differences between the observed data points (yi) and the predicted values from the model (f(xi, β)): minimize: Σ(yᵢ— f(xᵢ, β))² To find the optimal parameters (β), we define the objective function (also known as
