This investigations ignores this new moving escape aftereffect of Easter. Easter happens in April for most years in case Easter drops into the March, the amount of hobby can vary for this times getting specific series. This distorts the original estimates. An assessment of these two weeks cannot reflect the underlying development of your own study. The latest research together with ignores trading big date consequences.
