I am analyzing pricing for a new streaming service for a school project. My thought is to calculate the demand function of a player in the same industry and then calculate the optimal price. I am a little confused about calculating the demand function for Netflix. I have their subscription fees (converted to annual) since 2007 - x axis and subscribers - y axis. I am getting an upward slope.
Below is the output of regression.
Subscribers = 76.5 + 0.5 Fee_per_year
I would appreciate it if someone can point out what mistake I am making.
