This function calculates the f2 statistic as described in Moore and Flanner (1996).
Usage
f2calc(dis_data)
Value
The function returns the f2 statistic calculated from the observed dissolution data.
Arguments
dis_data
A data frame containing the dissolution data. The first column of the data frame should denote
the group labels identifying whether a given dissolution belongs to the "reference" or "test" formulation group.
For a given dissolution run, the remaining columns of the data frame contains the individual run's dissolution
measurements sorted in time. Alternatively, the user may provide a data object of class dis_data containing the
dissolution data. See the make_dis_data() function for the particular structure of the data object.
