    Graduate Testing Trend Stationarity in Time Series

    It is a series for energy demand. If the ADF test says it is non-stationary in level even if I include a trend, and that my series is I(1), is it valid to proceed without detrending since all the statistical tests don't show a time trend?

    For Undergrad: Harvard, Yale, Princeton, MIT, Stanford?

    I know many guys who graduated with a 3.2 GPA in mechanical engineering who started off making 65,000 dollars a year. They graduated with me from a school that is nowhere near as competitive and honored as those you mention.
