   Derivação matemática e pressupostos

   1. Coeficiente de con.rv na regressão por mínimos quadrados ordinários de con.winners.→ 0,0157718 (0.01577182397595691)
   2. Erro-padrão robusto à heterocedasticidade (HC1): a raiz da variância estimada do coeficiente.ep = √V_jj→ 0,000112007 (0.00011200667873969493)
   3. Intervalo de 95% de confiança: a estimativa mais ou menos o valor crítico da distribuição t de Student com 8804 graus de liberdade vezes o erro-padrão.IC = β ± c · ep

   Pressupostos do estimador

   • the conditional mean of the outcome is linear in the regressors
   • errors are independent across observations; their variance may differ
