peer agreement (net): +4Carryover-Effekt erster Ordnung Explanation: "First-order “carryover” means that we are only looking at the carryover effect from the immediately previous treatment. " In dem Link ist alles genau erklärt -------------------------------------------------- Note added at 13 mins (2008-04-30 13:23:00 GMT) -------------------------------------------------- "Carryover effects are when the results in subsequent treatments are influenced by treatments given in previous periods " Hier noch der Text im Zusammenhang: "Cross-Over Experiments Cross-over experiments are a special class of repeated measures experiments. Up to now the repeated measures experiments that we have been investigating, are where the experimental unit (patient, animal or field plot) is measured repeatedly after treatment and these measurements within patient are assumed to have some type of correlation. Only one treatment is applied to each of the experimental units. With a cross-over experiment, each experimental unit has more than one treatment applied throughout the trial and the treatment usually differs from one measurement period to another and these treatments are given in a randomly assigned sequence. Using a cross-over experiment allows for an increase in precision when less variability is expected within subjects than between subjects. One feature of cross-over designs with more than two periods, is the ability to measure any possible carryover effects. Carryover effects are when the results in subsequent treatments are influenced by treatments given in previous periods or may also be caused by a “learning effect” or “fatigue effect”. Researchers may try to get around a possible carryover effect by including a “washout” period between treatment periods. In other trials the carryover effect itself may be of interest. " "Note that for the treatment direct effect, the subscript t(ij) indicates that treatment t is a function of the sequence i and period j and for the carryover effect, the subscript r(ij) indicates that carryover r is a function of the sequence and the period. The indicator variable allows us to distinguish between the first period, where there is no carryover effect and the subsequent periods. First-order “carryover” means that we are only looking at the carryover effect from the immediately previous treatment. Second- and third-order carryover effects can also be evaluated. Second-order carryover is when the effect of a treatment carries over two periods, while third-order carryover is when the treatment effect carries over three periods. The occurrence of second- and third-order carryover is very rare in reality, so almost all designs and analyses concentrate only on first-order carryover.
