What is an interpolated rate?

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.

  1. 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.
  2. Plugging in the values for y1 and y2 at the end of the equation gives (5 – 3) or 2.
  3. 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

  1. x is the input value.
  2. known_ys are the known y-values.
  3. known_xs are the known x-values.
