Life processes are determined by the organism's genetic profile and multiple environmental variables. However the interaction between these factors is inherently non-linear [1]. Microarray data is one representation of the nonlinear interactions among genes and genes and environmental factors. Still most...

Patients in both groups were assessed at pre- and post-treatment while only the ICBT group was assessed 12 months after treatment completion. Health economic data were also gathered at all assessment points and analyzed using bootstrap sampling. Results Fifty of 61 patients (82%) completed the ...
Subsequently, we assessed the model fit of the original one-factor structure of CAS and OCS to the data independently with confirmatory factor analysis (CFA). A model was considered to be acceptable if it met the following criteria: (a) a comparative fit index (CFI) ≥ .90 and a Tucker...

To describe the distribution, we can calculate the center, spread, modality, and shape, as well as the presence of outliers. It is important to remember that what we have as the dataset, is called sample distribution in statistical analysis. If one repeats the same process of data collection...
Thus, advanced statistical tools and machine learning techniques may become essential to identifying patterns in the data and reaching reliable results. Some of the most important among these techniques, which may be applied to elemental analysis associated with the study of medical conditions, are ...
