There are two regression: the first is without dummy variables linear.r() the second one includes them(Online cards,Online purchases) linearD(). The function res allows yoy too see the residuals in ascending order.

#to see the coefficient
linear.r()
linearD()

#to see the total output
regression_output(linear.r())
regression_output(linearD())
# to see information
?linear.r()
?linearD()
?regression_output()
?res()
