Tests of the Efficient Markets Hypothesis
Austrian Journal of Statistics, 2016 This paper surveys various statistical methods that have been proposed for the examination of the efficiency of financial markets and proposes a novel procedure for testing the predictability of a time series. For illustration, this procedure is applied to Austrian stock return series.
