Uni-variate data sets are lists of values for the independent and the associated dependent variable.

Codification of types univariate data

The table below presents the labels for the different types of univariate data found in the collection (dark yellow cells to the far right of each row) and the usual field names used in the code. For the labels the independent and the dependent variables are separated by "-". Explanation as in previous section but the optional modifying factors now also include: W, weight; f, scaled functional response.
