Gaussian distribution linear regression
Web1.7.1. Gaussian Process Regression (GPR) ¶. The GaussianProcessRegressor implements Gaussian processes (GP) for regression purposes. For this, the prior of the GP needs to be specified. The prior mean is assumed to be constant and zero (for normalize_y=False) or the training data’s mean (for normalize_y=True ).

Consistency: If the GP specifies y(1),y(2) ∼ N(µ,Σ), then it must also specify y(1) ∼ N(µ 1,Σ 11): A GP is completely specified by a mean function and a
WebWe can learn the parameters in a linear-Gaussian model using [linear regression](linear_regression) . State-space models are an important example of linear-Gaussian models. Kalman smoothing can be [viewed](kalman_smoothing_as_bp) " as belief propagation in a linear-Gaussian model. WebWith simple linear regression, the residuals are the vertical distance from the observed data to the line. In this case, the tests for normality should be performed on the residuals, not the raw data. ... (Gaussian) distribution …
