medical health diabetes# What is extrapolation in regression?

Last Updated: 1st February, 2020

**regression**is the process you go throughto find the one line that best fits a given set of data points.Linear

**extrapolation**is when you evaluate a value for x intoyour equation of the line of best fit and get a resulting yvalue.

Similarly one may ask, what do you mean by extrapolation?

**Extrapolation** is an estimation of a value basedon extending a known sequence of values or facts beyond the areathat is certainly known. In a general sense, to **extrapolate**is to infer something that is not explicitly stated from existinginformation.

Also Know, why do we extrapolate graphs? **Graphs** are useful in Chemistry because they allowus to make predictions. Interpolate means to insert points betweenknown points on the **graph**. **Extrapolate** means toinsert points either before the first known point, or, after thelast known point on the **graph**.

Herein, when can you extrapolate data?

In engineering, it **will** always be necessary to**extrapolate**, given **data** from the present and previoustime, to some point in the future. For example, it is possible totake the current voltages of a system, and it may be necessary, inorder to respond appropriately to a system, to **extrapolate** afuture value.

What does extrapolation mean in business?

The aim is to take out the extremes of data from periodto period. Moving averages are often calculated on a quarterly orweekly basis. **Extrapolation** involves the use of trendsestablished by historical data to make predictions about futurevalues.
