In other words, the statistical results should be interpreted with caution and in light of all evidence/knowledge available. For example, if different castes have different determinants of FLFP and/or different average marginal effects of the determinants of FLFP, and there is a huge gap between two regions with respect to the shares of the population belonging to the different castes, the differences of these shares can bias the results. A great gap exists, for instance, between the Western and the Southern Region: the percentage of the population belonging to the upper caste in these regions are 34% and 21%, respectively.
