+
+$`c(u)=C`$
+
+> The constant model applies the the same constant value `c` to the selected metric regardless of the amount of users in the cell.
+
+*Model-specific Parameters*:
+
+`c` the constant value (*default* `0`)
+
+### Linear
+

+
+$`lin(u)=a*u+b`$
+
+*Model-specific Parameters*:
+
+`a` the slope (*default* `1`)  
+`b` y-axis intersection (*default* `0`)
+
+### Exponential
+

+
+$`exp(u)=a*e^{c(u-d)}+b`$
+
+*Model-specific Parameters*:
+
+`a` scaling factor (*default* `1`)  
+`b` y-axis offset (*default* `0`)  
+`c` exponent scaling (*default* `1`)  
+`d` x-axis offset (*default* `0`)
+
+### Logarithmic

+
+$`log(u)=a*ln(c(u-d))+b`$
+
+*Model-specific Parameters*:
+
+`a` scaling factor (*default* `1`)  
+`b` y-axis offset (*default* `0`)  
+`c` logarithm scaling (*default* `1`)  
+`d` x-axis offset (*default* `0`)

+
+$`cut(u)=a*\theta(c(u-d))+b`$
+
+> The cut-off model is based on the [Heaviside step function](https://en.wikipedia.org/wiki/Heaviside_step_function).
