Independent variable

independent variable
A driver of a change in the amount of a dependent variable. The independent variable is usually represented by "x", the dependent variable by "y", the rate of change by "b", and the fixed amount by "a" as in y = a + bx.

Independent Variable
A variable in a functional relation whose value determines the value or values of other variables, as x in the relation y = 3x2.

INDEPENDENT VARIABLE: A variable that is identified outside the workings of the model. Also termed an exogenous variable, an independent variable is in essence the "input" of the model.

where X is the independent variable (price, income, etc.) and Y is the dependent variable (quantity demanded, quantity supplied, etc).

Also, the number of periods that an independent variable in a regression model is "held back" in order to predict the dependent variable.

For example, an r squared of 75% means that 75% of the variability observed in the dependent variable is explained by the independent variable. Rally (recovery) An upward movement of prices. Opposite of reaction.

Regression coefficient Term yielded by regression analysis that indicates the sensitivity of the dependent variable to a particular independent variable. See: Parameter.

A linear relationship between a dependent variable and one or more independent variables plus a stochastic disturbance: Yi=b0+b1X1i+...+bnXni+ui.
Linearly homogeneous
Homogeneous of degree 1. Sometimes called linear homogeneous.

In statistics, linear regression is a technique for estimating the value of dependent variable from a set of one or more independent variables.

Notice that the activity or "cost driver" is shown as the independent variable on the X-axis; the resulting cost is shown on the Y-axis. A variable cost will begin at the origin (0,0) and will appear as a straight line.

(2) A measure (ranging in value from 1.00 to -1.00) of the association between a dependent variable (fund, portfolio) and one or more independent variables (index).

Distinguished from linear which sometimes is meant to imply that the function has no constant term; that it is zero when the independent variables are zero. An affine function may have a nonzero value when the independent variables are zero.

statistical method of identifying variables that differentiate groups a statistical technique designed to predict the groups or categories into which individual cases will fall on the basis of a number of independent variables.

Kurtosis risk applies to any kurtosis related quantitative model that relies on the normal distribution for certain of its independent variables when the latter may have kurtosis much greater than the normal distribution.

The presence of multicollinearity within the set of independent variables can cause a number of problems in the understanding the significance of individual independent variables in the regression model.

(1) A term used by economists to describe changes in dependent variables that tend to lag behind changes in the independent variables with which they are associated.

Stock market return was taken as dependent variable whereas Risk free rates as independent variables. Also, Pearson Correlation Matrix was also obtained through correlation model.

A measure of the goodness of fit of the relationship between a dependent and independent variable in a regression analysis-for instance, the percentage of the variation in the return of an asset explained by the market portfolio return.

Definition: The horizontal axis in a chart. It displays the range of values possible for the independent variable to take. In time series data, the x-axis represents time.
