One of the nonparametric regression methods that can be used for classification is Multivariate Adaptive Regression Splines (MARS) which is enhanced using bootstrap aggregating (bagging) with 50 replications. This method ...
• (wahyu sari yeni, 2019-07-22)
This article discusses an iterative method for solving nonlinear equations, by com- bining Ababneh's iterative method of order four with Newton's iterative method. The method has eight order of convergence with three ...
• (2020-08)
This paper discusses the combination of forecasting methods and linear programming to make a decision. Both of the methods are used to predict the sales of bakery products and to determine the best and most efficient ...
