This function develops a prediction of the users' rate of an innovation in the market, according to the number of triers

triers

a vector of percentage (0<triers<1) of known triers

This function calculates the rate of users in the population of a certain innovation according to known triers rate in that population and measured in a survey.

The measuring of triers is relatively easy. It is just a question of whether a person tried a product even once in his life or not. While measuring the rate of people who also adopt it as part of their life is more complicated since the adoption of a product is a subjective view of the individual. Mickey Kislev and Shira Kislev developed a formula to calculates the prevalence of users of a product to overcome this difficulty. The current function assists in calculating the users of a product based on the prevalence of triers in the population.
