FactorModel.AddLogSum Method

Adds a sum of (natural) log functions to be used as basis elements.

public void AddLogSum(
   double[] logCoeff,
   double[] coefficient,
   double[] constant,
   double[] exponent
);

logCoeff: An array where the k-th term is the coefficient of the whole k-th logarithm term within the sum.
coefficient: An array where the k-th term is the coefficient of the variable within the k-th logarithm term within the sum (i.e. coefficient as shown above).
constant: An array where the k-th term is the constant shift of the logarithm function of the k-th term within the sum (i.e. the constant term as shown above).
exponent: An array where the k-th term is the exponent of the logarithm term within the k-th element of the sum (i.e. n as shown above).

Where each of the elements of the sum given will take the following form:

logCoeff * logⁿ (coefficient * x + constant))
