Steps of the Extrapolation Process
There are following steps in the Extrapolation process:
- Data Collection: Collect all possible historical data or observations to have an accurate view on a wide range of time period to show the real trend or pattern behind.
- Data Analysis: The collected data should be analyzed diligently to identify the trends, patterns or correlations with the variables using statistical techniques like regression analysis or time series analysis.
- Selecting Extrapolation Techniques: Appropriate extrapolation techniques should be selected based on the data nature and on the trend, when making predictions. They may include linear extrapolation, polynomial extrapolation, regression analysis and time series forecasting methods, among others.
- Model Fitting: Select the fitted model or curve applying it to the observed data points such that to describe the trend underlying data being analyzed as well as to minimize errors or deviations.
- Extrapolation: Build one model if data was observed or curve beyond the range of observed data to anticipate future trends. Be careful in extrapolation as most often the foundation assumptions are not accurate and it may be imprecise.
def extrapolation_(q, r):
result = (q[0][1] + (r - q[0][0]) /
(q[1][0] - q[0][0]) *
(q[1][1] - q[0][1]));
return result
# dataset
q = [[ 5.2, 8.7 ], [2.4, 4.1 ]];
# Sample Value
r = 2.1;
# Finding the extrapolation
print"Value of y at x = 2.1 :",extrapolation_(q, r)
Output:
Value of y at x = 2.1 : 3.6071428571428577
What is Extrapolation?
Extrapolation is a method used in mathematics, statistics, and science to estimate values beyond a known range. It involves using existing data to predict future values or to estimate unknown values within a dataset. In this article, we learn more about extrapolation along with it’s importance, techniques and advantages.
