The key is to start with the individual (idiographic) and then only move to group-level (nomothetic) generalisations when appropriate. Idio-graphic + nom-ethetic = Idionomic.

• Collect sufficient data at the lowest meaningful level.
  • This is Level 1 — individual participants, couples, families, or countries.
  • May involve intensive longitudinal data to capture meaningful within-unit patterns.
• Build a model for each Level 1 unit.
  • For example, use a simple ARIMA model for each individual to estimate the link between a process (X) and an outcome (Y).
• Evaluate whether aggregation is appropriate.
  • Use techniques like meta-analysis to assess the pooled effect size and the heterogeneity (e.g., I²).
• Aggregate if appropriate. If the pooled effect accurately represents most individual data.
• Explore functional subgroups if heterogeneity is high. Look for functionally homogeneous subgroups.
