generateCowbellConcept: Expresses the fitting formula and the value range of the variables.
Description
Generates a concept which is basically the formula used for the regression analysis and minimal and maximal
values of the dependent and two independent variables. As this package creates a very specific regression model
the formula is always of the form Dest ~ SrcA * SrcB. If one of the minimal and maximal values are omitted,
the minimum or maximum value of the data set will be used later on.
The formula essentially specifying the names of the dependend variable (here Dest)
and the two independent variables (here SrcA, SrcB). Example: Dest ~ SrcA * SrcB.
minDest
The a prior known minimal value the dependend variable (Dest) can have.
maxDest
The a prior known maximal value the dependend variable (Dest) can have.
minSrcA
The a prior known minimal value the first dependend variable (SrcA) can have.
maxSrcA
The a prior known maximal value the first dependend variable (SrcA) can have.
minSrcB
The a prior known minimal value the second dependend variable (SrcB) can have.
maxSrcB
The a prior known maximal value the second dependend variable (SrcB) can have.
Value
List of the aggregate information. This is used in the regression analysis.
