求翻译：脉冲反应函数描述的是在随机误差项上施加一个标准差大小的冲击后对内生变量的当期值和未来值所带来的影响，方差分解则将系统中某一个变量的波动分解成由系统中各变量冲击所带来的影响部分，并记录系统中每一变量冲击影响的比例。是什么意思？

The impulse response function describes the impact of endogenous variables of the current value and future value to impose a standard deviation of the size of the impact on the random error variance decomposition of a variable is system of a volatility decomposition by the system the ratio of the va

Impulse response function is described in the Random errors on the size of a standard deviation of the impact of the variable and the value and future value, and the impact of the variance decomposition in the system will be a variable of the fluctuations in the system exploded into the variable imp

The pulse responded the function description is exerts a standard deviation size after the stochastic error term the impact to cause trouble the quantity to in when the age and the future value will bring the influence, the variance will decompose then some variable undulation will decompose the sys

Pulse response function describes the size of the standard deviation of the random error term imposed on a internal variable values in the current period after impact and the impact of future values, variance decomposition is a variable of the system wave apart from the impact brought about by the i
