How can I handle missing data in time series analysis?
An example of an AI chatbot conversation about handling missing data in time series analysis.
What are some common methods to handle missing data in time series?
Common methods include interpolation, forward filling, backward filling, and using statistical models to estimate missing values.
Can you explain how interpolation works?
Interpolation estimates missing values by using the values around them. For example, linear interpolation connects two known points to estimate the missing value.
Are there any risks associated with these methods?
Yes, using these methods can introduce bias or distort the data if not applied carefully, especially in non-linear trends.
What should I consider when choosing a method?
Consider the nature of your data, the amount of missing data, and the potential impact on your analysis results.
