Using a sequential design, we study several cohorts, or age groups, over a long period of. Sequential methods provide a formal framework by which clinical trial data can be monitored as they accumulate. In sequential designs, the observations are analysed before the next response point is selected.

This strategy implies that the design depends on the selected response surface model.

The results from interim analyses can be used either to modify the design of the remainder of the trial or to stop the trial as soon as sufficient evidence of either the presence or absence of a treatment effect is available. Given a specified pattern of information levels, for example, equally spaced The test with index ∆ has critical values of the form bk = c˜1 (ik/ik)∆−0.5, ak = δ √ ik −c˜2 (ik/ik)∆−0.5, k = 1,.,k. The exploratory sequential design would be labeled qual→quant (creswell & plano clark, 2018).
