On this episode of Assessment Matters, host and Value Base CEO Will Jarvis talks with veteran appraiser and data geek Keith Wolf about what truly drives credible valuations: data and variable interactions.

They unpack:

• How mass and fee appraisal really overlap
• Why stats and data science matter for everyday appraisal
• How misunderstanding multicollinearity can lead you badly astray

If you’re an assessor or appraiser using models, this one’s for you.
