Relationship, requires input

Semiconductor fabrication plant requires input Industrial process water

The stored status is what a reviewer approved. The level below it is what the overlapping data support; the two are shown side by side and only a human moves the status.

The edge as stored

Semiconductor fabrication plant requires input Industrial process water2 evidenceEstablished relation

Semiconductor fabrication plant depends on Industrial process water.

Mechanism

Wafer processing rinses with ultrapure water between steps; a fab uses millions of gallons a day. Recycling reduces intake but not the need.

Statistical evidence

No analysis has been stored for this edge. The causal.analyze_all job runs monthly over every edge with a catalog metric linked to both entities; edges without a series on both ends are not analysed.

Not computed

Causal estimate

A causal estimate needs at least 20 overlapping periods and was not attempted for this edge yet.

What each rung means

Levels

  1. Level 0: No association found

    the overlapping data show no significant association.

  2. Level 1: Correlation only

    statistically associated in the overlapping periods; no direction, no mechanism.

  3. Level 2: Predictive lead/lag

    one series historically contains predictive information about the other.

  4. Level 3: Mechanism supported

    a documented physical, economic or institutional mechanism with cited evidence.

  5. Level 4: Causally supported

    a backdoor-adjusted estimate that survived refutation, on stated assumptions.

  6. Level 5: Established relation

    follows from engineering, accounting or scientific structure.
