A cross-sequential design is a research method that combines both a longitudinal ... (e.g. 20, 25, 30, 35, 40, 45, 50, 55, and 60 years) as in a cross-sectional ...
In medical research, epidemiology, social science, and biology, a cross-sectional study (also known as a cross-sectional analysis, transverse study, prevalence study) is a type of observational study that analyzes data from a population, or a representative subset, at a specific point in time—that is, cross-sectional data. [definition needed]
Cross-sectional data differs from time series data, in which the same small-scale or aggregate entity is observed at various points in time. Another type of data, panel data (or longitudinal data ), combines both cross-sectional and time series data aspects and looks at how the subjects (firms, individuals, etc.) change over a time series.
In statistics and econometrics, a cross-sectional regression is a type of regression in which the explained and explanatory variables are all associated with the same single period or point in time. This type of cross-sectional analysis is in contrast to a time-series regression or longitudinal regression in which the variables are considered ...

Cross sectional view of sequences To describe such data, we may look at the columns and consider the cross-sectional state distributions at the successive positions. The chronogram or density plot of a set of sequences renders these successive cross-sectional distributions.
For curative treatments or rapidly changing conditions, cross-over trials may be infeasible or unethical. Crossover studies often have two problems: First is the issue of "order" effects, because it is possible that the order in which treatments are administered may affect the outcome. An example might be a drug with many adverse effects given ...
