Neste relatório, estimamos modelos logísticos (glm binomial) para três indicadores lógicos de resiliência (resil_math, resil_read, resil_scie), tendo como preditoras as escalas de TIC da PISA 2022. Apresentamos resultados globais e por país (variável CNT). Nas tabelas mostramos labels completos; nos gráficos usamos versões curtas (quebradas ou truncadas) para melhor legibilidade.

11 Interpretação dos resultados

  • OR > 1: associação positiva; OR < 1: associação negativa. Intervalos que não cruzam 1 sugerem significância a 5%.
  • Tabelas com labels completos ajudam a interpretação substantiva; gráficos usam rótulos curtos para preservar legibilidade.

12 Recomendações analíticas e cautelas

  • Multicolinearidade entre escalas: verifique VIF; considere regularização (glmnet).
  • Pesos PISA: para inferência oficial, usar svyglm com pesos e réplicas (BRR).
  • Controles: ESCS, sexo, repetência, status migrante, língua em casa etc.
  • Diagnósticos de separação/quase-separação, sobretudo em países com amostras pequenas.
