The long-term interest rates, for example, determine when homeowners refinance their mortgages in mortgage pricing, play a dominant role in life insurance, decide when one should exchange a long bond to a short bond in pricing an option. In this paper, for a one-factor model, we reveal tha...
The shortages are allowe d and deterioration rate is time dependent. The objective is to determine the optima l tot l cost and the optimal time schedule of the plan for the proposed model. To ill ustrate the results of this model, numerical example is presented.年份: 2015 ...
"A convergence rate in the invariance principle for martingale difference arrays is obtained. The rate obtained depends essentially on the asymptotic behavior of the conditional variances. An example which shows the rate obtained is exact is shown. It will be also remarked, by an example, that th...
Do the Math:Now, you can calculate using the following churn rate formula: For example, if you started with 1,000 customers and lost 50, your churn rate would be: Understand What It Means:This percentage tells you how many customers you’re losing over time. A lower churn rate is genera...
I did the math and calculated the return to be 0.44%. Not good and in the range of current CDs. What am I missing? Hersh Stern (ImmediateAnnuities.com) 2015-07-16 14:14:36 Hi Ernest, On the amortization schedule I included with your quotes, you'll see that it shows you in detail...
Example 1. In Figure 1, we select the parameter values for model (6) as follows: S ( 0 ) = 0.8 , I ( 0 ) = 0.1 , R ( 0 ) = 0.1 , α = 0.2 , β = 0.4 , μ 1 = μ 2 = μ 3 = 0.2 , ρ = 0.12 , γ = 0.06 , ζ = 0.8 , σ = 0.35 , Y = ( 0 , +...
One of the possible techniques that can help to visualize the deformation rate of the dataset is to plot the main components of the tensor using strain-rate diagrams, where concentrations of strain-rate patterns can be displayed as vector fields (see, for example, the ones in geodetical ...
For example, if your business had 250 customers at the beginning of the month and lost 10 customers by the end, you would divide 10 by 250. The answer is 0.04. You then multiply 0.04 by 100, resulting in a 4% monthly churn rate. If that math is as intimidating to you as it is ...
For example, Hu used PCA to reduce the characteristics of attacks in network security situation prediction by using BRB18. (2) Structure reduction methods, which can reduce the number of rules. For example, Zhou proposed an automatic adding and deleting criterion for belief rules in BRBs based...
(Math Program, doi: 10.1007/s10107-014-0826-5 , 2014 ) provided a counter-example showing that the ADMM for \(N\geqslant 3\) may fail to converge without further conditions. Since the ADMM for \(N\geqslant 3\) has been very successful when applied to many problems arising from real ...
