Logistic
The logistic regression algorithm applies nonlinear recursive least-squares techniques to optimize
the following cost function:
N

which is the sum of the squares of the residual errors,
where:

the independent variable list
x

=
the dependent variable list
N
=
the dimension of the lists
This technique attempts to estimate the constants
possible.
SinReg
The sine regression algorithm applies nonlinear recursive least-squares techniques to optimize the
following cost function:
