NettetLinear models. Linear models assume that each time sample is independent of the next. This is tenable for positron emission tomography (PET) data because the nature of the measurement is essentially steady state. Usually, PET data are acquired while holding brain states constant, using an appropriate task or stimulus and waiting until steady ...

"NettetSimple linear regression. In the simplest case, the regression model allows for a linear relationship between the forecast variable y y and a single predictor variable x x : yt = β0 +β1xt +εt. y t = β 0 + β 1 x t + ε t. An artificial example of data from such a model is shown in Figure 5.1. The coefficients β0 β 0 and β1 β 1 denote ... " - Linear model poly55
