The fundamental condition required is that for each pair of states ij the longrun rate at which the chain makes a transition from state to state equals the longrun rate at which the chain makes a transition from state to state ij ji 11 Twosided stat Time series observed in the practise are sometimes nonstationary In this case they should be transformed to some stationary time series if possible and then be analysed Two types of stationarity exists strong or strict and weak stationarity Weak sta Time series observed in the practise are sometimes nonstationary In this case they should be transformed to some stationary time series if possible and then be analysed Two types of stationarity exists strong or strict and weak stationarity Weak sta Key words and phrases GARCH model higherorder moments nonlinear time series strict stationarity 1 Introduction Consider the following nonlinear time series model 11 where i 1 p j 1 q is a sequence of independent identically distributediid random va The Classic 45 and up The Classic with Color 95 and up The Classic with Highlights 115 and up The Classic with Full Highlights 135 and up The Classic Fusion 165 and up The Classic Fusion with Full Highlights 185 and up BUBBLES GUARANTEE BUBBLES Hair Jozef. .
