In this study, the value of the dependent variable is repayment ratio that has been computed as the ratio of amount
of loan repaid to the total amount due from formal sources of credit. Thus, the value of the dependent variable
ranges between 0 and 1 and a two-limit Tobit model has been chosen as the appropriate econometric model. The
two-limit Tobit was originally presented by Rossett and Nelson (1975) and discussed in detail by Maddala (1992)
and Long (1997). The model derives from an underlying classical normal linear regression and can be represented
as:
