Kwiatkowski phillips schmidt shin test statistic value is less than any of the below than we would accept the null i e the variable is stationary.

This is white noise around a trend so it is definitely a stationary process but has a trend. Test the hypothesis that the log wages series is a unit root process with a trend i e difference stationary against the alternative that there is no unit root i e trend stationary.
