Dear SPM Experts: Could anyone recommend any good textbooks explaining Statistical Parametric Mapping/General Linear Models, in laymen's term and/or in a step-by-step approach, e.g. starting from the simplest of linear models to models with covariates (when to center covariates around condition or overall mean), and furthermore to residual analysis... I thank you very much in advance.
