xls.objfun

A data.frame object which is returned by <code>xls.prep</code>. Tip: <code>xls.prep</code>'s <code>.$data</code> sub object returns the data.frame

data

Symbolic error column's name. By default, it is named "error_symbolic" by <code>xls.prep()</code>

error_column_name

A numeric vector including error weights by order.

error_weights

An integer which represents how many steps further the parameters will be optimized for each data point.

error_ahead_level

Automatically used in <code>xls.fit()</code>
No need to use if the objective function is not specifically desired to be achieved.

Given the date column as an ascending entry, future errors are included in the sum of squares of error that should be minimized based on the number of steps and weights you determine. Thus, it is prevented that the variables affect each other's coefficients unrealistically.
