A binomial logit model is estimated to determine the ownership of a Bank Debit card in a
selected Suburb in South Africa. The Bank Debit card is a binary variable with Y=1 for debit
card holder and zero otherwise. The number of households is 60. The estimated binomial logit
model is given by 𝐿𝑖
𝐿𝑖 = -0.55574 + 0.0012𝐵𝑖 - 0.1202𝑇𝑖 – 1.352𝑅𝑖 + 1.452𝐸𝑖
z = (−0.7316) (1.97) (−2.567) (-1.98) (2.89)
McFadden R2 = 0.1007,
LR statistics = 7.6073,
Prob(LR statistics) = 0.0155
where 𝐵𝑖= account balance in rands
𝑇𝑖 = frequency of ATM transactions
𝑅𝑖 = 1 if interest is paid on the account balances and zero otherwise.
𝐸𝑖= 1 if employed in formal sector and zero if in the informal sector.
