This is key to avoiding color publication costs in some journals as it can be made greyscale and folks can still figure out which line is which. Lines are not only different colors, one is dashed and one is solid.Features of this plot that are somewhat unique: Well, technically it’s a cumulative incidence plot since the line starts a 0% and creeps up as events happen rather than starting at 100% and dropping down as events happen. In this analysis we needed to put together a Kaplan-Meier plot for Figure 2 (sometimes called a survival plot).

With a quick application, IRB, and DUA, you can get world-class datasets from landmark clinical trials like ACCORD, SPRINT, TOPCAT, etc. This is an incredible resource for datasets. We obtained the data from the NIH/NHLBI BioLINCC repository.

We also provide a downloadable excel template.In the early Winter of 2019, we had a paper published in JAMA: Network Open using the TOPCAT trial dataset looking at association between beta-blocker use at baseline and incident heart failure admissions.

Here we discuss how to calculate the Macaulay Duration Formula along with practical examples. This is a guide to the Macaulay Duration Formula. When rates increase and become larger, it becomes increasingly important to understand the bond yield relationship however, using a linear approximation like duration will contain a lot of errors.

One important point to consider is that Duration is a good approximation for an option free bond with small changes in interest rates. Just as mean, standard deviation, beta act as a measure for equities, Macaulay Duration is for fixed income securities. Understanding duration helps an investor in determining the correct pick of fixed income security.

Relevance and Use of Macaulay Duration Formula All this information can be accessed easily, and using the above formula Duration can be calculated. Macaulay Duration considers the time, coupon payment, the current yield, par value of the bond and the price to arrive at a number. The Macaulay Duration Formula can be calculated by using the below explanation:

Or any one of the dates or both are not excel valid dates.

If the numbers are invalid for either Coupon, yield, and frequency.

It occurs if the settlement date is greater than or equal to the maturity date.

Possible Errors and their meanings in excel: In the above calculation basis argument has been omitted in this case the default value of 30/360-day count basis is used. Let us consider a $100 par bond with a Settlement date as 1 st April 2015, a Maturity date as 31 st March 2025, coupon rate of 6% paid quarterly with a yield of 8%

Frequency = Number of Coupon Payments Paid in A Year:.

Settlement = Date of the Settlement of The Security.

Syntax: DURATION (settlement, maturity, coupon, yield, frequency, ) The Present Value of Cash flow is calculated as After calculating the discount factor, we will multiply it with the cash flows to get the present value.Īfter calculating the discount factor, we will multiply it with the respective cash flow to get the present value and sum all the cash flows to get the bond’s Macaulay Duration.ĭiscount Factor for 6 months = 1 / (1 + 6%/2) We will first calculate the discount factors for all the periods using the formula 1 / (1+ r) n, where r is the coupon rate and n is the total number of periods for which it has to be compounded. Let us now calculate Macaulay Duration using these cash flows. We can expect the following cash flows to occur: 6 months: $3, 1 year: $3, 5 years: $3, 2 years: $3, 5 years: $3, 3 years: $3, 5 years: $3, 4 years: $103. The coupon rate is 8% p.a with semi-annual payment. Let us take a Bond A $100 value bond that pays a 6% coupon rate and matures in four years. Let us take another example and calculate Macaulay Duration using the longer method. Using the above formula, Macaulay Duration of Bond A is at 3.57 while Macaulay Duration of Bond B is at 4.13. Macaulay Duration = Modified Duration * (1 + (Yield/ Frequency)) Macaulay Duration is calculated using the formula given below
