To calculate your Viral Coefficient, follow these steps:
- Take your current number of users (e.g 100)
- Multiply by the average number of invitations or referrals that your user base sends out (100 x 10)
- Find the percentage of referrals that took the desired action, for example, signed up to be a new user.
Why it is called K factor?
K Factor is a metric for app developers that reveals your app’s virality, by measuring how many additional users each of your existing users brings along to the app. The term K Factor actually comes from the world of medicine, where it’s used as a metric to measure how quickly a virus spreads.
What is a good K-factor?
This means that to achieve true “growth,” a K-Factor of greater than 1 is the target. Even a K-Factor of 1.01 is a good K-Factor as it means that a game will keep spreading, even if it takes a long time to so. Technically speaking there is no reason why a paid game / app can’t also go viral.
What is a virial coefficient in chemistry?
Virial coefficients appear as coefficients in the virial expansion of the pressure of a many-particle system in powers of the density, providing systematic corrections to the ideal gas law. They are characteristic of the interaction
What is the difference between B2 and B3 virial coefficient?
The second virial coefficient B 2 {displaystyle B_{2}} depends only on the pair interaction between the particles, the third ( B 3 {displaystyle B_{3}} ) depends on 2- and non-additive 3-body interactions, and so on.
How do you get virial expansion from kinetic energy?
The virial expansion is obtained from this expansion by observing that . In this manner one derives . These are quantum-statistical expressions containing kinetic energies. Note that the one-particle partition function contains only a kinetic energy term.
