For example, economists have found that in some circumstances there is a lead-lag effect between large-capitalization and small-capitalization stock-portfolio prices. [ 2 ] (A loosely related concept is that of lead-lag compensators in control theory, but this is not generally referred to specifically as a "lead-lag effect.") [ citation needed ]
He has developed two methods for studying interactions between actors, the “leading –lagging, LL- strength method” and the “angle frequency method”. The first extends the analysis of associations with analyses of “leading” and “lagging” relationships for cyclic phenomena.
Angle notation can easily describe leading and lagging current: . [1] In this equation, the value of theta is the important factor for leading and lagging current. As mentioned in the introduction above, leading or lagging current represents a time shift between the current and voltage sine curves, which is represented by the angle by which the curve is ahead or behind of where it would be ...

Economists, analysts, policymakers and investors take the economy's temperature by examining regularly released data sets called economic indicators. There are all kinds of economic indicators ...

Lagging indicators are indicators that usually change after the economy as a whole does. Typically the lag is a few quarters of a year. The unemployment rate is a lagging indicator: employment tends to increase two or three quarters after an upturn in the general economy. [citation needed]. In a performance measuring system, profit earned by a ...
For example, with seven variables and four lags, each matrix of coefficients for a given lag length is 7 by 7, and the vector of constants has 7 elements, so a total of 49×4 + 7 = 203 parameters are estimated, substantially lowering the degrees of freedom of the regression (the number of data points minus the number of parameters to be ...
