A binomial logit model is estimated to determine the purchase of a house using a bank loan in a selected suburb in South
A binomial logit model is estimated to determine the purchase ofa house using a bank loan in a selected suburb in South Africa. Thepurchase of a house using a bank loan is a binary variable with Y=1for purchasing and zero otherwise. The number of households is 100.The estimated binomial logit model is given by πΏπΏοΏ½ππ πΏπΏοΏ½ππ = 0.55 +0.57πΏπΏπΏπΏπΏπΏπΈπΈππ + 0.112πΏπΏπΏπΏπΏπΏπ΄π΄ππ + 1.352π»π»ππ + 0,452ππππ β1.452π

The probability that a householdwith earnings of R10 000 will own a house? (4) ii. The rate ofchange of probability at the earnings level of R10 000?

Clearly outline the steps(4) 2.4 Explain how you can use regression restrictions todetermine the impact of explanatory variables on the purchase of ahouse. You can use any of the variables given.
