请问这个面板数据单位根的检验是有单位根还是没有单位根呢?
Panel unit root test: Summary
Series: S
Exogenous variables: Individual effects
Automatic selection of maximum lags
Automatic selection of lags based on SIC: 0 to 12
Newey-West bandwidth selection using Bartlett kernel
Cross-
Method Statistic Prob.** sections Obs
Null: Unit root (assumes common unit root process)
Levin, Lin & Chu t* -1.05737 0.1452 9 1178
Null: Unit root (assumes individual unit root process)
Im, Pesaran and Shin W-stat -3.26370 0.0005 9 1178
ADF - Fisher Chi-square 41.5020 0.0013 9 1178
PP - Fisher Chi-square 56.9331 0.0000 9 1191
这个LLC是接受原假设的,也就是说有单位根,但是其他3个test都是拒绝原假设,没有单位根.
那么最后结论怎么定呢?
