Is it convenient to talk at the moment? http://directit.co.ke/index.php/stmap_18wt5ee.html viraldrugaddictions.com Each time a report is published, statisticians rework the estimates for the entire time period being evaluated — not just the most recent year. Statistical models and data improve over time, so the numbers often shift. A report released in 2013, therefore, may not be comparable to a report released in 2012.
