X+Y Loading Plot VIP Exclusive

🔀 What is this?

This is a hybrid loading plot that places X variables (causes) and Y variables (results) on the same chart.

It allows you to see at a glance: Which causes (X) have the greatest impact on results (Y)?

🧐 How to read?

• Points:
  • Blue points: Usually represent X variables.
  • Red points: Usually represent Y variables.
• Relationships:
  • If a blue point (X) and a red point (Y) are close together, it indicates they are highly positively correlated (e.g., adding catalyst increases yield).
  • If they are opposite each other across the origin, it indicates highly negative correlation (e.g., too high temperature reduces yield rate).

🛠️ How to use?

Note: This chart has a lasso function for selecting abnormal parameters.

• Find key factors: Focus on the Y you care about most (e.g., "yield rate") and see which X is closest to it - that's the key.
• Optimize process: If you want to improve Y, adjust the X variables that are positively correlated with it.
