Die Autokorrelation der Parameterwerte sollte gering
The autocorrelation of parameter values should be low
Literally: The autocorrelation of-the parameter-values should low [be]
In 15 Seconds
- Technical term for ensuring data points are independent and not repetitive.
- Essential for high-level German academic and data science contexts.
- Signals deep expertise and attention to mathematical detail.
Meaning
This phrase means that in a sequence of data, individual values shouldn't be too similar to the ones that came right before them. It's like saying your data points should be independent thinkers rather than just copying their neighbors' homework.
Key Examples
3 of 6Presenting research results
Die Autokorrelation der Parameterwerte sollte gering sein, damit die Ergebnisse repräsentativ sind.
The autocorrelation of the parameter values should be low so that the results are representative.
Reviewing a colleague's code
Ich habe mir den Output angesehen; die Autokorrelation der Parameterwerte sollte geringer ausfallen.
I looked at the output; the autocorrelation of the parameter values should turn out lower.
Writing a formal lab report
Um die Konvergenz zu gewährleisten, sollte die Autokorrelation der Parameterwerte gering bleiben.
To ensure convergence, the autocorrelation of the parameter values should remain low.
Cultural Background
German universities emphasize 'Methodenlehre' (methodology). Students are often tested more on their understanding of diagnostics like autocorrelation than on their final results. In German engineering (Ingenieurwesen), precision is a point of pride. Using Latin/Greek terms like 'Autokorrelation' instead of 'Selbst-Abhängigkeit' signals professional belonging. German journals (like 'Statistik in Deutschland') have very strict stylistic guidelines that mandate the use of the genitive over 'von'-constructions. Even in the international tech scene in Berlin, German data scientists will switch to this formal phrasing during code reviews to ensure there is no ambiguity.
Use 'gering' not 'niedrig'
In academic German, 'gering' is the preferred adjective for abstract statistical measures. 'Niedrig' is for physical heights or temperatures.
Genitive is King
Never say 'Autokorrelation von den Werten' in a paper. It will mark you as a non-native or uneducated writer immediately.

What It Means
This is a heavy-hitter from the world of statistics and data science. Autokorrelation describes how much a variable correlates with a delayed version of itself. If it's high, your data is 'sticky' and predictable. If it's low, each value brings fresh, independent information. Think of it like a conversation. If every sentence you say is almost identical to the last, the 'autocorrelation' of your speech is too high. People will get bored! In science, low autocorrelation means your model is healthy and exploring new ground.
How To Use It
You use this when you're analyzing results from a simulation or a complex model. It’s a way to critique the quality of a data set. You’ll usually see it in written reports or hear it in high-level technical meetings. It sounds very professional and precise. Just drop it into a conversation about algorithms. You will instantly sound like the smartest person in the room. Just make sure you actually have some data to back it up!
When To Use It
Use this during a master's thesis defense or a technical presentation. It’s perfect for peer-reviewing a colleague's research paper. If you are working with Markov Chain Monte Carlo (MCMC) methods, this phrase is your best friend. It shows you care about the mathematical integrity of your work. It’s also great for sounding impressively nerdy at a tech conference. Use it when the data looks a bit too 'smooth' or repetitive.
When NOT To Use It
Do not use this at a birthday party. Unless you are at a party full of statisticians, people will look at you blankly. Avoid it when talking to your barista about your morning coffee. It’s far too formal for grocery shopping or casual texting with friends. If you tell your partner their mood has high autocorrelation, you might find yourself sleeping on the couch. Keep it in the lab or the office.
Cultural Background
Germany is world-famous for its engineering and scientific precision. This phrase is a prime example of Fachsprache (technical language). Germans value clarity and exactness in professional settings. Using specific terms like Autokorrelation instead of 'repetitive data' is expected in high-level German academia. It reflects a culture that prizes deep expertise and rigorous methodology. It’s not just about being smart; it’s about being technically accurate.
Common Variations
You might hear Die Korrelation ist zu hoch for a simpler version. In a more active sense, someone might say Wir müssen die Autokorrelation senken. If the data is perfect, you’d say Die Werte sind weitgehend unkorreliert. Sometimes people just say Der Mix ist schlecht if they are being informal in a lab. But for the full 'expert' effect, stick to the original phrase.
Usage Notes
This is a C1-level technical expression. It requires a solid grasp of genitive case and technical vocabulary. It is strictly formal and should be reserved for academic or professional contexts where data integrity is being discussed.
Use 'gering' not 'niedrig'
In academic German, 'gering' is the preferred adjective for abstract statistical measures. 'Niedrig' is for physical heights or temperatures.
Genitive is King

The 'Fachidiot' Trap
Only use this phrase with people who have a background in math or science. To anyone else, you will sound like a robot.
