The aim of study is to forecast global tourist visits and compare the forecasting methods determine best method using random forest, single exponential smoothing double smoothing, respectively. These are applied in visit data West Nusa Tenggara Province. Random familiar frequently utilized forecasting. In addition, three have great accuracy for time series data, such as visits. used this from 2...

Two quadrature-based algorithms for computing the matrix fractional power $A^\alpha$ are presented in this paper. These based on double exponential (DE) formula, which is well-known its effectiveness improper integrals as well treating nearly arbitrary endpoint singularities. The DE formula transforms a given integral into another that suited trapezoidal rule; process, interval transformed an i...

-In this paper, the asymptotic bit operation cost of a family of quadrature formulas, especially suitable for evaluation of improper integrals, is studied. More precisely, we consider the family of quadrature formulas obtained by applying k times the variable transformation x : sinh(y) and then the trapezoidal rule to the transformed integral. We prove that, if the integrand function is analyti...
