Let's say, we are given a dataset for 100 people analyzing their modal choice. Only two models are there: Car, Walk. The dataset looks like as follows: Person 50 people 50 people Income HH Size 10,000 2 20,000 3 So, the dataset is like 50 people has 10K income and 2 members in the House. The remaining 50 people has 15K income and 3 members in the house. We develop a model for car and below is the model: Variable Estimates Wald Standard Error Constant 2.96 9.055 ? Income 1.50 4.188 ? Household size 0.50 7.148 ? a. Please calculate the standard error of the table. [5] b. Now, if the income increase by 10%, what will be the effect (elasticity) of income on car choices? [10]
