In the field of biomedical signal processing (e.g. pathological speech signal processing), it is often the case that the data we analyse were obtained from the two independent measurements. To investigate whether the measurements provide statistically relevant information, we can use so called “test re-test analysis” tool (TRAT).

Software TRAT provides the functions for the computation of so called “test re-test variability” [%], “intra-class correlation coefficient” (ICC) and its associated p-value (significance value of correlation), Pearson’s correlation coefficient and its p-value. The tool also provides function to visualize the correlation diagrams (linear relationship between the measurements). It is written in the MATLAB programming environment. The testing script can be used to test functionality of the software.
