models: A five-year moving average model. The sales in the 6th week may be predicted as: 375+395+360+400+3805=382 salesA weighted moving average model with weights of 0.1, 0.1, 0.2, 0.3, and 0.3 for years 1 through 5, respectively. For year 1 through 5: 375×0.30.3=375375×0.3+395×0.30.3+0.3=385375×0.3+395×0.3+360×0.20.3+0.3+0.2=378375×0.3+395×0.3+360×0.2+400×0.10.3+0.3+0.2+0.1=381375×0.3+395×0.3+360×0.2+400×0.1+380×0.10.3+0.3+0.2+0.1+0.1=381An exponential smoothing model with a year 1 forecast of 380 and α = 0.2.

modeling the data (Dybka). Based on the proposed ERD, the enrollment, course completion, course sequence, advisor and thesis committee reports can easily be generated at any time. Entities Four entities extracted from the data presented in the reports include student, course, professor and thesis committee. Relationships and Cardinalities The relationships between the entities were based on the following business rules: Many students enroll to many courses (mandatory, many-to-many) Many courses have many students (mandatory, many-to-many)’ A course may have a prerequisite course (optional, one-to-one) A course may be a prerequisite to many courses (optional, one-to-many) A student may have a thesis...
model function approximations of the form yx=i=1nωi∅(x-x1)The function y(x) (approximating function) is represented as a sum of the radial basis functions (N), each having a different center (Xi) and a weighted coefficient (Wj). Since the approximating function is linear in value, it is easier to employ the matrix method to derive the weight coefficient. This type of the equation is applied where prediction of series is required as well as when controlling nonlinear systems that present unstable behaviors. Essentially, Radial Basis Functions are typically trained by a two-step algorithm. Akima Interpolation This is a continuously differentiable spline interpolation built from third order...

model explains only 1.97% of the variation in course evaluation is explained by the model, because the model does not explain 98.03%, we can conclude that it is a worse model. The t-test for beauty has a p-value of 0.009, which is less than 0.05 therefore we can reject the null hypothesis at 95% confidence level and conclude that beauty has a significant effect on the course evaluation. The coefficients of the variables are 0.0983013 for beauty and 4.02936 for constant. This explains that for every unit increase in the beauty there is a significant increase in course evaluation by 0.0983013. The correlation between beauty and course evaluation is positive therefore any change in beauty will...

model has overestimated the height by the difference of 40.5-40.2 which is 0.3 inches. Question 3 It is appropriate to determine the height of the girl during birth, considered as month zero. Once this has been achieved, it is good to substitute 0 in place of x. The function looks like this: F(0)=3.1√(0)+19 =0+19 =19 Once this has been achieved, it is possible to determine the height at the 10th month. In this case, you should substitute the value 10 for x. The function yields: F(10)=3.1√(10)+19 =3.1(3.162)+19 =9.8+19 =28.8 Question 4 The determination of the average amount of change can be obtained accordingly. It calls for the calculation of the average change as through: The average change in...
Model (CAPM) is a model that shows the relationship between systematic risk and expected return for assets, especially stocks (Campbell, 1993). We have three components that make up the expected returns, and they are as follow: Risk-free rate, Beta of the security and Expected market return. Risk-free rate The risk-free rate refers to the minimum return an individual should gain within a certain period of time when he makes any investment, which has zero risks. In reality, this cannot hold as there is no investment that has zero risks. Many times, the risk-free rate is used as a benchmark by an investor in decision making. The interest of government bonds are the ones used as the risk-free rate....

model of the business such that the long term growth span is not applicable. The other reason could be that the company is in need of cash for the purposes of completing its purchase of the competing company (Williams, 2016). On the other hand, the company may do the same with the objective of venturing in a given project. In some circumstances, when a company is in urgent need of cash, it may not be restricted to small or averaged stocks (Williams, 2016). On the same note, in some cases, companies may hesitate to reduce the growth rate of its dividends with the objective of ensuring reduction in the cash outflow for the purposes of financing mergers and acquisitions. Finally, a company may...
