Develop the best logistic regression model that can predict the wage by using the
combination of any following variables: total unit (X2), constructed unit (X3), equipment
used (X4), city location (X5) and total cost of a project (X6). Make sure that you partition
your data with 60% training test, 40% validation test, and default seed of 12345 before
running the logistic regression (15 points)

Wage - X1 Total Unit - X2 Contracted Units - X3 Equipment Used - X4 City Location - X5 Total Cost - X6

The model is not well fitted because all the explonatory variables are insignificant at 5% of level of significance. i.e(p-value > alpha value)

A university would like to develop a regression model to predict the point differential for games played by its men's basketball team. A point differential is the difference between the final points scored by two competing teams. A positive differential is a win for the university's team and a negative differential is a loss. For a random sample of games, the point differential (y) was calculated, along with the number of assists (x1), rebounds (x2), turnovers (x3) and personal fouls...
