What is an interpolated rate?
Interpolation is a statistical method by which related known values are used to estimate an unknown price or potential yield of a security. Interpolation is achieved by using other established values that are located in sequence with the unknown value.
What is the interpolated Treasury rate?
An interpolated yield curve (I curve) is a yield curve derived by using on-the-run Treasuries. Because on-the-run Treasuries are limited to specific maturities, the yield of maturities that lies between the on-the-run treasuries must be interpolated.
Is an example of interpolation method?
Let’s suppose a gardener planted a tomato plant and she measured and kept track of the growth of the tomato plant every other day. This gardener is a very curious person, and she would like to estimate how tall her plant was on the fourth day….Examples of Interpolation.
| Day | Height (mm) |
|---|---|
| 5 | 8 |
| 7 | 12 |
| 9 | 16 |
How can we calculate interpolation?
Find the interpolated value mathematically.
- Plugging in the values for x, x1, and x/2 in their places gives (37 – 30)/(40 -30), which reduces to 7/10 or 0.7.
- Plugging in the values for y1 and y2 at the end of the equation gives (5 – 3) or 2.
- Multiplying 0.7 by 2 gives a product of 1.4.
How do you calculate interpolation?
Know the formula for the linear interpolation process. The formula is y = y1 + ((x – x1) / (x2 – x1)) * (y2 – y1), where x is the known value, y is the unknown value, x1 and y1 are the coordinates that are below the known x value, and x2 and y2 are the coordinates that are above the x value.
How do you interpolate a rate in Excel?
To perform linear interpolation in Excel, use the FORECAST function to interpolate between two pairs of x- and y-values directly. This simple method works when there are only two pairs of x- and y-values….Linear Interpolation in Excel
- x is the input value.
- known_ys are the known y-values.
- known_xs are the known x-values.
