Continuous <strong>Fuzzy</strong> <strong>Set</strong>: Direct<br />
Calibration Method<br />
• Used <strong>to</strong> transform interval-scale variables in<strong>to</strong><br />
membership scores between 0 and 1<br />
• Three ‘qualitative’ anchors<br />
1. Threshold for full membership<br />
2. Threshold for full non-membership<br />
3. Cross-over point (maximum ambiguity)<br />
E.g. Firm size based on European Union enterprise size<br />
classes (Fiss, 2011)<br />
1. Full membership: 250 + employees<br />
2. Full non-membership: < 10 employees<br />
3. Cross-over point: 50 employees<br />
• This calibration can be performed using fs<strong>QCA</strong> software
