This is important for some applications as phase shift between the voltage and current waveforms is one parameter of power quality that is monitored and without simultaneous sampling it is difficult to determine whether that shift is from the instrumentation or the circuit. Figure 11: Design a ...
You must collect data from a sample of potential customers as part of your research to determine their preferences and purchasing behavior. But how can you be sure that the information you get from your sample is accurate for all of the people who might buy your product? The idea of ...
In this article the authors aim to present a series of considerations, regarding the research carried out in the last 8 years, which starting from Big Data have posed different methodological problems related on the one hand to sampling and on the other to the conception of erro...
This is because,by default, the GA4 data is imported to BigQuery only from the date you first connected your GA4 property to your BigQuery project. If you want historical GA4 data in your BigQuery project, you will need to backfill GA4 data in BigQuery by creating a new data transfer. Ta...
ANOVA is a statistical method used to analyze variance observed within a dataset by dividing it into two sections: 1) Systematic factors and 2) Random factors. Anova can determine which factors have a significant effect on a given set of data and supports additional analysis onmethodological facto...
Passive detection of service faults: In most cases, O&M personnel can determine the fault scope based on only complaints received from users or work orders dispatched by related service departments. This means that O&M personnel cannot perceive faults quickly and can only handle the faults passive...
Stick High Threshold: This value is used to determine whether the throttle stick is fully raised. It’s useful for functions such as activating the OSD menu. It’s important to note that Stick Low/High Thresholds are not the same as stick endpoints and do not affect the throttle stick’s...

Split data to avoid too much data in a single partition. Check method You can specify a threshold based on your service requirement. If any threshold is exceeded, a BigKey is generated. The number of rows of a single partition key cannot exceed 100,000. The size of a single partition ...
