%description
Performs binary classification via Group Method of Data Handling (GMDH) -
type neural network algorithms. There exist two main algorithms available
in GMDH() and dceGMDH() functions. GMDH() performs classification via GMDH
algorithm for a binary response and returns important variables. dceGMDH()
performs classification via diverse classifiers ensemble based on GMDH
(dce-GMDH) algorithm. Also, the package produces a well-formatted table of
descriptives for a binary response. Moreover, it produces confusion
matrix, its related statistics and scatter plot (2D and 3D) with
classification labels of binary classes to assess the prediction
performance. All 'GMDH2' functions are designed for a binary response (Dag
et al., 2019,
<https://download.atlantis-press.com/article/125911202.pdf>).
