WebJul 16, 2024 · Intercept = 14.6 – 2.8 * 3 = 6.2 Therefore, The desired equation of the regression model is y = 2.8 x + 6.2 We shall use these values to predict the values of y for the given values of x. The performance of the model can be analyzed by calculating the root mean square error and R 2 value. Calculations are shown below. WebVideo transcript. - [Voiceover] So here I'd like to talk about what the gradient means in the context of the graph of a function. So in the last video, I defined the gradient, but let me just take a function here. And the one that I had graphed is x-squared plus y-squared, f of x, y, equals x-squared plus y-squared.
