"solid" and "discrete" LINE of Relationship/Related/Correlation AMONG OCCURRENCES

If by “solid” and “discrete” line of relationship/correlation among occurrences you mean the terminology for describing how strongly occurrences are connected, the distinction can be expressed like this:

---

---

• Solid relationship / correlation — the occurrences have a clear, consistent, and relatively strong connection. When one occurs, the other tends to occur in a predictable way.
• Discrete relationship / correlation — the occurrences are separate or distinguishable, with the relationship occurring only under particular conditions or between particular occurrences. “Discrete correlation” is less standard terminology and may need a more precise term depending on your field.

---

If you're looking for a single technical phrase meaning a clear and continuous connection among occurrences, possibilities include “strong association,” “systematic relationship,” “consistent correlation,” “direct relationship,” or “robust correlation.”

---

If you tell me the field/context (e.g., philosophy, statistics, sociology, linguistics, physics, or your own theoretical framework), I can give you the exact terminology.
