The Weighted‐Average Lagged Ensemble
A lagged ensemble is an ensemble of forecasts from the same model initialized at different times but verifying at the same time. The skill of a lagged ensemble mean can be improved by assigning weights to different forecasts in such a way as to maximize skill. If the forecasts are bias corrected, then an unbiased weighted lagged ensemble requires the weights to sum to one. Such a scheme is call...
متن کاملA new method for determining the optimal lagged ensemble
We propose a general methodology for determining the lagged ensemble that minimizes the mean square forecast error. The MSE of a lagged ensemble is shown to depend only on a quantity called the cross-lead error covariance matrix, which can be estimated from a short hindcast data set and parameterized in terms of analytic functions of time. The resulting parameterization allows the skill of fore...
متن کاملLagged cells.
The timing of the retinal input to the lateral geniculate nucleus is highly modified in lagged cells. Evidence is reviewed for how the responses of these cells are generated, how their structure and function differs from their nonlagged neighbors, and what their projections to cortex might do.
متن کاملCross-Lagged Panel Analysis
Cross-lagged panel analysis is an analytical strategy used to describe reciprocal relationships, or directional influences, between variables over time. Cross-lagged panel models (CLPM), also referred to as cross-lagged path models and cross-lagged regression models, are estimated using panel data, or longitudinal data where each observation or person is recorded at multiple points in time. The...
متن کاملWhat Explains the Lagged Investment E§ect?
The best predictor of current investment at the firm level is lagged investment. This lagged-investment e§ect is empirically more important than the cash-flow and Q e§ects combined. We show that the specification of investment adjustment costs proposed by Christiano, Eichenbaum and Evans (2005) predicts the presence of a lagged-investment e§ect and that a generalized version of their model is c...
