In finance, we often refer to the delay that occurs between pre-filtered data and the filter itself as the "time lag". This time lag is a crucial concept to understand, as it can greatly affect the accuracy and reliability of financial data. Essentially, the time lag refers to the period of time that passes between when data is collected and when it is processed. It is important to keep this in mind when analyzing financial data, as it can impact decision making and overall financial health.
