how to rewrite in a better way: I am considering using three logistic regression models to answer my first research question. The first model would include family SES and control variables, the second would add school-related variables based on the first model, and the third would add test-taking ability variables based on the second model.

Previously, comparing the coefficients of different logistic regression models was challenging because the coefficients obtained from these models are probabilities. To compare probabilities, all conditions must be consistent, including the variables and sample sizes. However, NAME_1 (2019) has developed methods to overcome this limitation, allowing us to compare the coefficients of different logistic regression models. This will enable us to determine the actual coefficients of key variables for each model and answer our first research question: how family SES, school characteristics, and test-taking ability influence inequality in access to different HEIs. This analysis is also coherent within the methodology.

From a theoretical perspective, we can connect these three variables in this way. First, we address the influence of SES on educational attainment, which has been a subject of controversy. Some scholars believe that SES has a large influence, while others think its influence is small. The controversy arises mainly due to two factors: the use of different indicators of SES and the omission of important variables such as school characteristics and students' test-taking Provide exactly two different responses that are separated with 6 asterisk symbols: ******.
