However, the level of education is also a way to a “good marriage”, so that the simultaneity issue with a high level of education remains limited. The number of children could also be determined simultaneously with participation in the labour force. ( Didier et al 2014). The probability of participation of each woman using the linear model and the proportion of individuals whose probability of participation is not comprised between 0 and 1 (extreme values) were predicted. These latter individuals were removed, and the results were re-evaluated. A prediction is considered accurate if the predicted probability of participation is below 0.5 and the woman actually does not work, or the predicted probability is more than 0.5 and the woman actually works.
