Statistical methods time series

What are the methods of calculating time series?
Augmented Dickey-Fuller is the statistical test that we run to determine if a time series is stationary or not.
The Augmented Dickey Fuller test checks the null hypothesis that a unit root is present in a time series sample.
The alternative hypothesis is usually stationarity or trend-stationarity..
What is the best statistical test for time series?
The two most generally used methods for time series forecasting are exponential smoothing and ARIMA models, which provide complementary approaches to the problem.
While exponential smoothing models try to explain the data's trend and seasonality, ARIMA models strive to characterize the data's autocorrelations..
What is time series trend analysis methods?
Time series analysis refers to a particular collection of specialised regression methods that illustrate trends in the data.
It involves a complex process that incorporates information from past observations and past errors in those observations into the estimation of predicted values..

What are the guidelines for data quality in time series analysis?

The typical guidelines for data quality apply here:

and is uniform across sets

When dealing with time series analysis, it is even more important that the data was collected at consistent intervals over the period of time being tracked.
This helps account for trends in the data, cyclic behavior, and seasonality.
