If a pattern appears when a dependent variable is plotted against time, one should use time series analysis instead of regression analysis.

Time series analysis is a statistical method used to analyze time series data, which is a series of data points in which each data point is associated with a timestamp. Time series analysis is used to identify patterns and trends in the data, as well as to make forecasts about future values. Since regression analysis is used for analyzing the relationship between two or more variables, it may not be appropriate for analyzing time series data where the dependent variable is plotted against time. Therefore, time series analysis is more suitable in this case.
