I obtained a model fit: Sales = 1020 -8.8*Price +2.1*online reputation

after substituting the value of online reputation, I came out with following demand equation: 1036.8-8.8*Price Now to take out the revenue (sales*Price) I converted it to revenue function: 1036.8*Price - 8.8*Price^2

Now can I implement MAB for finding the price in order to maximize the revenue

  • $\begingroup$ No I am not, is it a good idea. If not what shall I use. I m using R $\endgroup$ Jan 13, 2017 at 15:55

I completely don't understand why you're trying to use anything more complicated than find an vertex of the parabola described by simple quadratic equation.

In the general situation $y = ax^2 + bx + c$ the vertex point has coordinates: $(-\frac{b}{2a}, -\frac{\Delta}{4a})$

In your case we're tring to find the vertex of the parabola described by $$y = -8.8 \cdot x^2 + 1036.8 \cdot x$$

Your coefficients are $a=-8.8, b = 1036.8, c = 0$ and $\Delta = b^2 - 4ac = (1036.8)^2$

Maybe I don't see something, but at the first glance it's so simple.
