In regression analysis, partial leverage (PL) is a measure of the contribution of the individual independent variables to the total leverage of each observation. That is, if h i is the i th element of the diagonal of the hat matrix, PL is a measure of how h i changes as a variable is added to the regression model.
Partial leverage (PL) is a measure of the contribution of the individual independent variables to the total leverage of each observation. That is, PL is a measure of how h i i {\displaystyle h_{ii}} changes as a variable is added to the regression model.
Partial regression plots are most commonly used to identify data points with high leverage and influential data points that might not have high leverage. Partial residual plots are most commonly used to identify the nature of the relationship between Y and X i (given the effect of the other independent variables in the model).
Psychological projection is a defence mechanism of alterity concerning "inside" content mistaken to be coming from the "outside" Other. [1] It forms the basis of empathy by the projection of personal experiences to understand someone else's subjective world. [1]
Partial least squares (PLS) regression is a statistical method that bears some relation to principal components regression and is a reduced rank regression; [1] instead of finding hyperplanes of maximum variance between the response and independent variables, it finds a linear regression model by projecting the predicted variables and the observable variables to a new space of maximum ...

Knowledge retrieval seeks to return information in a structured form, consistent with human cognitive processes as opposed to simple lists of data items. It draws on a range of fields including epistemology (theory of knowledge), cognitive psychology, cognitive neuroscience, logic and inference, machine learning and knowledge discovery, linguistics, and information technology.
Psychophysiology measures exist in multiple domains; reports, electrophysiological studies, studies in neurochemistry, neuroimaging and behavioral methods. [5] Evaluative reports involve participant introspection and self-ratings of internal psychological states or physiological sensations, such as self-report of arousal levels on the self-assessment manikin, [6] or measures of interoceptive ...
