Most research on the performance and risk of hedge funds are based on calculations that just use the data from one index provider. Also most product providers and even more and more investors are using hedge fund indices for benchmarking purposes. As some academic articles pointed out, the world...

This article discusses the effect of an autocorrelated error structure on the interpretation of traditional significance tests, especially the t-test and R2 measure It emphasizes first-order serial correlation, a common and often serious problem that researchers using time series data may...

A modified Sims' test which bypasses the traditional Aristotelian causality can be used to determine the appropriate causal ordering among Important economic variables This test can provide valuable insight into many economic relationships, thereby providing additional information for policy...
