Standard errors in brackets; “pro” denotes probit and “log” logit models, the first two columns contain the baseline model, the model with female * household size interaction is indicated with “int” and the children-only model with “chi”. Pseudo-R² is denoted with “r2_p”, the statistic and p value of the chi-square global significance test as “chi2” and “p”, and the log-likelihood as “ll”
