• Variable bitrate — (VBR) is a term used in telecommunications and computing that relates to the bitrate used in sound or video encoding. As opposed to constant bitrate (CBR), VBR files vary the amount of output data per time segment. VBR allows a higher bitrate… …   Wikipedia

• Explained variation — In statistics, explained variation or explained randomness measures the proportion to which a mathematical model accounts for the variation (= apparent randomness) of a given data set. Often, variation is quantified as variance; then, the more… …   Wikipedia

• Explained sum of squares — In statistics, an explained sum of squares (ESS) is the sum of squared predicted values in a standard regression model (for example y {i}=a+bx {i}+epsilon {i}), where y {i} is the response variable, x {i} is the explanatory variable, a and b are… …   Wikipedia

• Omitted-variable bias — In statistics, omitted variable bias (OVB) occurs when a model is created which incorrectly leaves out one or more important causal factors. The bias is created when the model compensates for the missing factor by over or under estimating one of… …   Wikipedia

• Algol variable — Algol variables or Algol type binaries are a class of eclipsing binary stars. When the cooler component passes in front of the hotter one, part of the latter s light is blocked, and the total brightness of the binary, as viewed from Earth,… …   Wikipedia

• intervening variable — A variable , used in the process of explaining an observed relationship between an independent and dependent variable(s) , such that X →T →Y where T is the intervening variable which is used to explain the X →Y relationship. For example, if X is… …   Dictionary of sociology

• Endogenous Variable — A classification of a variable generated by a statistical model that is explained by the relationships between functions within the model. For example, the equilibrium price of a good in a supply and demand model is endogenous because it is set… …   Investment dictionary

• dependent variable — Within a particular study, analysis, or model, a dependent variable is the social element whose characteristics or variations are to be explained by reference to the influence of other, prior, so called independent variables . For example, a… …   Dictionary of sociology
