![]() ![]() ![]() Part of the reason for this is also because the difference between inferential and descriptive use of statistics is often blurred, and could be mistaken by novice epidemiologists. A significant part of the statistical estimate is based on the assumption that the correct statistical model is estimated. The predominant reason for this practice is the widespread notion among academics that “statistically significant data is noteworthy, and one that is not statistically significant is not”. We may use these term interchangeably in the discussion below. ![]() Data dredging is recognized by several names such as ‘fishing trip’, ‘data snooping’, ‘p-hacking’ and so on. This may lead to an exponential increase in the risk of inclusion of large quantities of false positive results, thereby corrupting the data that was meant to be originally reported. Impact of data dredging on epidemiologyĭata dredging is defined as “cherry-picking of promising findings leading to a spurious excess of statistically significant results in published or unpublished literature”.The following discussion will attempt to define data dredging and provide an answer to such questions. To learn more about the Dino6 or our other dredging machines, contact us online or call us at 91 today.What is data dredging? How does it affect the p-value? What is its impact on the world around us? We have a range of small-scale sediment removal systems to meet all your lagoon, pond or river dredging needs. When it comes to sediment removal from lagoons, Geoform International is the obvious choice. GeoForm International: The Lagoon Dredging Equipment Experts This is the dredging system you need for your lagoon. The pump itself is an extremely abrasion-resistant hydraulic submersible dredge pump that is quite durable. With 65 horsepower, a working depth of anywhere from 14 inches to 13 feet and a 1500 GPM flow, this barge has all the pumping power and depth capacity to effectively clear accumulated sludge, sediment, trash and debris from your lagoon. At less than four thousand pounds, the Dino6 can excavate areas of your lagoon that a larger hydraulic dredge will not be able to reach. It is small enough to easily maneuver through small lagoons, even though it is more durable than much heavier and more expensive machines. The Dino6 is ideal for removing unwanted sediment from your lagoon. We have worked tirelessly to develop the best possible lagoon dredging equipment, and the result is superior dredging barges like the Dino6 dredge. View the Dino6 Best Equipment for Dredging a Lagoon Dredging is also an effective way to clear sediment in shallow industrial lagoons in the wastewater lagoon industry, where you may be trying to conserve return water. While agitation can compact some sediment in a lagoon, this will not work on lagoons that have allowed sediment and sludge to sit for a long time and become dense and adhered to the lagoon bottom. Removing the sediment can deepen and widen your lagoon while also improving its look and odor. Why Dredge Your Lagoon?Ī lagoon filled with sediment is unattractive due to the level of muck and debris floating around in it. ![]() The dredging system goes into the lagoon and uses a high-torque direct-drive cutter head to release the sediment and move it to the dredge pump, allowing you to easily remove the sediment from the lagoon. Lagoon dredging involves using a dredging system, like the Dino Six dredge, containing a powerful pump to excavate the sediment. When you need to remove sediment from a lagoon and standard methods of agitation are not effective, lagoon dredging is the preferred approach. ![]()
