ERA/DC (eingensystem realization algorithm using data correlation) adopts the data correlation approach when constructing the Hankel matrix with impulse response data.

An efficient de-noising algorithm for extracting the impulse response function of system;

The substitutive effect between competitive energy sources in China is being studied with the help of impulse response functions and using a model constructed according to the vector auto-regression(VAR) technique.

Then we study the response model of economic growth to energy shock through VAR and analysis of the impulse response function.

The deflection pulse response function in the general Duhamel integration is got by using integral transform and the program of corresponding numerical inverse integral is worked out.

Using the relevant time-series data of Jiangxi province from 1980 to 2006,using the impulse response function and variance decomposition method of VAR model,analysis relationship between financial support agriculture and farmers net income of Jiangxi from the total financial support agriculture.

Based on Vector Auto-regression Model, the paper applies the pulse response function and the difference decomposition to analyze the dynamic correla.

Based on the monthly data from 1996 to 2007,by constructing the effected factor of domestic price model,this paper analyzes the long-term and short-term effects of exchange rate of RMB,amount of the money supply and prices of import refined oil to the CPI,RPI and PPI through a series of methods,such as ADF, regression analysis,IRF and variance decomposition.

It proposes that it is possible to analyze quantitatively the dynamic impact of major macroeconomic variables on prices by creating the VAR model and its Impulse Response Function(IRF) and Variance Decomposition(VD).

This paper,by means of cointegration,vector error correction( VEC) model and impulse response function( IRF) ,fully ananlyzes the impact of fluctuation in RMB exchange rate on trade structure both in short term and in the long run.

Split Monte Carlo for impulse responses on the infrared indoor channels on the basis of Phong s model;

Based on the results of structural breaks test of oil price and OPEC output,this paper sets Vector Error Correction Model in three sub-periods and compares the influences of OPEC output on the oil price with the methods of impulse response function and variance decomposition.

This paper establishes a dynamic model on basis of the rate of inflation,pure income of peasants,the social security,save and deposable income of urban,analynizing the path of impulse response of the demand for life insurance to the variations by VAR model and impulse response function.

The basic impulse response function is introduced,and that of elliptical flaws is studied.

Finally, the basic impulse response function is illustrated.
