A review of the methods used in trials of antipsychotics, despite stating that the overall quality is " rather good ," reported issues with the selection of participants ( including that in schizophrenia trials up to 90 % of people who are generally suitable do not meet the elaborate inclusion and exclusion criteria, and that negative symptoms have not been properly assessed despite companies marketing the newer antipsychotics for these ); issues with the design of trials ( including pharmaceutical company funding of most of them, and inadequate experimental " blinding " so that trial participants could sometimes tell whether they were on placebo or not ); and issues with the assessment of outcomes ( including the use of a minimal reduction in scores to show " response ," lack of assessment of quality of life or recovery, a high rate of discontinuation, selective highlighting of favorable results in the abstracts of publications, and poor reporting of side-effects ).

* Central composite design, an experimental design in response surface methodology for building a second order model for a response variable without a complete three level factorial

These methods are followed in experimental design.

These principles are widely used intuitively in various kinds of proofs, demonstrations and investigations, in addition to being fundamental to experimental design.

In general usage, design of experiments ( DOE ) or experimental design is the design of any information-gathering exercises where variation is present, whether under the full control of the experimenter or not.

In the design of experiments, the experimenter is often interested in the effect of some process or intervention ( the " treatment ") on some objects ( the " experimental units "), which may be people, parts of people, groups of people, plants, animals, etc.

As with other branches of statistics, experimental design is pursued using both frequentist and Bayesian approaches: In evaluating statistical procedures like experimental designs, frequentist statistics studies the sampling distribution while Bayesian statistics updates a probability distribution on the parameter space.

experimental design, "... it is clearly not ethical to place subjects

Skeptics claim that there is a lack of a viable theory of the mechanism behind ESP, and that there are historical cases in which flaws have been discovered in the experimental design of parapsychological studies.

Unfortunately, the fatal Miles accident was attributed at least partly to the unproven aerodynamics of the J-car design, as well as the experimental chassis ' strength.

The first British experimental design ( the destroyer HMS Velox ) had been constructed in 1901 and as a result Tirpitz had set up a special commission to develop turbines.

Pseudorandom number generators are widely used in such applications as computer modeling ( e. g., Markov chains ), statistics, experimental design, etc.

: Blocking is the arrangement of experimental units into groups ( blocks ) consisting of units that are similar to one another.

Even so, the response styles of the two groups were similar, indicating that the experimental group still based their choices on the length of the run sequence.

The Beatles developed along similar lines, creating various modernist musical effects on several albums, while musicians such as Frank Zappa, Syd Barrett and Captain Beefheart proved even more experimental.

* Blocking ( statistics ), in the design of experiments, the arranging of experimental units in groups ( blocks ) which are similar to one another

Their experimental setup was similar to the preceding experiments in that it used a mixture of deuterated acetone, deuterated benzene, tetrachloroethylene and uranyl nitrate.

This suggested similar surgery in humans, and early reports in prominent medical journals ( January 8 ) are that the same effect is seen in humans, at least the small number who have participated in the experimental surgical program.

Two similar zero-length launch experimental programs were carried out by the US Air Force and by the Soviet VVS at around the same time in the late 1950s.

A positive control is a procedure that is very similar to the actual experimental test but which is known from previous experience to give a positive result.

There are other meanings in other technical cultures ; among experimental physicists and hardware engineers it may designate any random object of unknown purpose ( similar to hackers ' use of frob ).

Furthermore, a similar joke website claims that Peeps are insoluble in acetone, water, diluted sulfuric acid, and sodium hydroxide ( the web site also claims that the Peeps experimental subjects sign release forms ).

It didn't get beyond the experimental stage, though its principle of operation ( described in Siemens British patent 2074 of 1860, and by Siemens in The Theory of the Gas Engine ) appears to be similar to the commercially successful Brayton engine of 1872.

NHK developed an experimental teletext system along similar lines, called CIBS (" Character Information Broadcasting Station ").

Her success there led to her briefly opening an experimental school which was an early attempt to introduce kindergarten methods ( love instead of harshness for discipline ; interest instead of compulsion to impart knowledge ), but this, like other similar attempts at this time was not accepted and soon closed.

Behaviorism placed the human being as an animal subject to reinforcements, and suggested to place psychology as an experimental science, similar to chemistry or biology.

In this way, the empirical method is similar to the experimental method.

The other probabilities can be determined in a similar manner, allowing a direct experimental test of the inequality.

On October 16, 2007, Yahoo announced that it would discontinue Yahoo 360 °, including bug repairs ; the company explained that in 2008 it would instead establish a " universal profile " similar to the Yahoo Mash experimental system.

Citalopram-induced macropsia is similar to zolpidem-induced macropsia since both types have been observed in relatively few cases, and neither of the drugs ’ side effects can be supported by experimental evidence.

The Experimental Game is similar to the Quick Game, except the player can also control red ants, spiders and has access to a set of experimental tools.

He became professor of experimental physics, first at Palermo and then at Rome, and was appointed to a similar situation at Turin in 1748.

Duccio ’ s style was similar to Byzantine art in some ways, with its gold backgrounds and familiar religious scenes but also different and more experimental.

On the basis of a number of experimental trials similar to the one described above, Leavitt formed these conclusions:

The history of the turntable being used as a musical instrument has its roots dating back to the 1930s, 1940s and 1950s when musique concrète and other experimental composers ( such as John Cage, Halim El-Dabh, and Pierre Schaeffer ), used them in a manner similar to that of today's producers and DJs, by essentially sampling and creating music that was entirely produced by the turntable.

An important philosophy of experimental biology holds that radically different organisms solve similar problems in similar ways.
