1 Numerical Methods for Differential Equations 1 2 NUMERICAL METHODS FOR DIFFERENTIAL EQUATIONS Introduction Differential equations can describe nearly all systems undergoing change. They are ubiquitous is science and engineering as well as economics‚ social science‚ biology‚ business‚ health care‚ etc. Many mathematicians have studied the nature of these equations for hundreds of years and there are many well-developed solution techniques. Often‚ systems described by differential

software that was used in order to predict the future sales was StatTools. StatTools provided me with four different methods (Moving Averages‚ Simple‚ Holt’s & Winters’ exponential smoothing) of forecasting to identify the most accurate prediction possible. With a Means Absolute Percentage Error (MAPE) of 3.72% the Holt’s exponential smoothing method was determined to be the best method of predicting monthly wine sales for the next sixteen months (Figure 2).

Solutions 1. Note that P (uj ≤ Xj ≤ vj ) = e−λuj − e−λvj ‚ and fXj (x|uj ≤ Xj ≤ vj ) = λe−λx /{e−λuj − e−λvj }. Hence‚ Xj (λ) ≡ Eλ (Xj |Xj ∈ [uj ‚ vj ]) = 1 uj exp(−λuj ) − vj exp(−λvj ) + . λ exp(−λuj ) − exp(−λvj ) The log-likelihood function based on the full sample is n ∑ l(θ) ≡ l(θ; X1 ‚ · · · ‚ Xn ) = n log λ − λ Xj ‚ j=1 which yields the MLE based on full sample θ(X1 ‚ · · · ‚ Xn ) = n/ ∑ 1≤j≤n Xj . Now the E-step is Q(λ) = Eλ0 {l(θ) | Xj ∈ [uj ‚ vj ] for

selected to represent the relation. The function will be algebraically approached using the numerical values of the data points. Through the use of technology‚ the parameters will be plugged in to illustrate that function electronically. The function will be observed and any limitations with the model will be indicated. The function might need refinement according to any outliers/ anomalies‚ also to better represent the trend. The model function and a given function by the programme will be compared.
