r : Number of purchases of the company’s own brand
Pr : Probability of r purchases
M : Average number of purchases per unit period (number of votes per person for the company’s own brand within a given period)
K : Parameter determining the shape of the probability distribution (calculated from the penetration rate and M)
K is designed to be calculated using a separate custom formula.
