A statistical technique used to establish the relationship of a dependent variable (fund or portfolio) and an independent variable (index) This shows how similar or dissimilar the selected component, less the risk free proxy, is to the market proxy
Usually linear regression is used to explain and/or predict The general form is Y = a + bX + u, where Y is the variable that we are trying to predict; X is the variable that we are using to predict Y, a is the intercept; b is the slope and u is the regression residual The a and b are chosen in a way to minimize the squared sum of the residuals The ability to fit or explain is measured by the R-squared
A statistical technique for relating the sensitivity of the detector array to a constant value that compensates for any irregularities in the detector A least squares fit is performed to determine the regression model In a two-dimensional graphical representation this regression model would be a line that minimizes the sum of the squares of the vertical distances of the intensity values from the line
A form of statistical modelling that attempts to evaluate the relationship between one variable (termed the dependent variable) and one or more other variables (termed the independent variables) It is a form of global analysis as it only produces a single equation for the relationship thus not allowing any variation across the study area Geographically Weighted Regression is a local analysis form of regression
the analysis or measure of the association between a dependent variable and one or more independent variables, usually formulated as an equation in which the independent variables have parametric coefficients, which may enable future values of the dependent variable to be predicted
A statistical technique used to establish the relationship of a dependent variable (e g excess return) and one or more independent variables (e g exposure to market, size, and value risks) Slope coefficients measure the sensitivity of the dependent variable to changes in the independent variables By measuring exactly how large and significant each independent variable has historically been in its relation to the dependent variable, the future value of the dependent variable can be estimated Essentially, regression analysis attempts to measure the degree of correlation between the dependent and independent variables, thereby establishing the latter's predictive values
the slow lowering of sea level and/or raising of the edge of a contin-ent such that the shoreline slowly moves away from the center of the continent, exposing more land above sea level Marine sediments deposited during regres-sion get coarser in size as you move vertically upward through the pile
The statistical counterpart or analog of the functional expression, in ordinary mathematics, on one variable in terms of others Thus, regression curve, regression coefficient
Reduction in the size of a tumor The opposite of progression Regression can be partial or it can be complete (meaning that the tumor completely disappears from a particular place in the body)
A statistical technique that uses the association between the independent variable(s) and the dependent variable as means of prediction May be described as either simple linear (1 independent variable) or multiple regression (more than one independent variable) Selection procedures for multiple regression include forward selection, backward selection, and stepwise selection (see Appendix D)
In biometrics it is the dependence of a variable called "dependent" on another variable called "independent variable" The regression coefficient is the numerical measure of the rate of change of the independent variable on the dependent variable The straight or curved regression line indicates the nature of a regression on a graph with the dependent on the Y axis and the independent on the X axis
returning to a former state the relation between selected values of x and observed values of y (from which the most probable value of y can be predicted for any value of x) (psychiatry) a defense mechanism in which you flee from reality by assuming a more infantile state
An appraisal principle that states that, between dissimilar properties, the value of the better-quality property is affected adversely by the presence of the lesser-quality property (See appraisal)
A statistical method for studying and expressing the change in one variable associated with and dependent upon changes in another related variable or group of variables A line that shows the relationships between two variables
is a statistical procedure to establish the relationship between two variables, for example fund and benchmark excess returns Each point is plotted on a graph and a line of best fit calculated The slope of the line is called the regression Beta The intercept with the axis is called Alpha
In statistics, a process for determining a line or curve that best represents the general trend of a data set. Linear regression results in a line of best fit, for which the sum of the squares of the vertical distances between the proposed line and the points of the data set are minimized (see least squares method). Other types of regression may be based on higher-degree polynomial functions or exponential functions. A quadratic regression, for example, uses a quadratic function (second-degree polynomial function) to produce a parabola of best fit
A mathematical technique used to explain and/or predict The general form is Y = a + bX + u, where Y is the variable that we are trying to predict; X is the variable that we are using to predict Y, a is the intercept; b is the slope, and u is the regression residual The a and b are chosen in a way to minimize the squared sum of the residuals The ability to fit or explain is measured by the R-square
A term coined by Galton for the tendency of the quantitative traits of offspring to be closer to the population mean than are their parents' traits It arises from a combination of factors - dominance, gene interactions, and environmental influences on traits
the movement of points in an orbit in the direction opposite from the motion of the orbiting body For example, the Moon travels from west to east, but its nodes are regressing from east to west S
Functioning in a less-highly-evolved, less effective way (as one did at an earlier time), or in self-defeating ways Regression is often triggered by external threats or stress; it can be intentionally elicited and utilized in the service of personal development through the Mentoring process
