The ln
function can be used in custom filters and table calculations to get the natural logarithm of a value.
Syntax
ln(value)
The ln
function takes the logarithm of a value
to the base of the mathematical constant e.
Examples
The ln
function can be used to model exponential growth linearly by taking ln
of the dependent variable. For example:
ln(order_items.growth_rate)
Things to know
ln
can be used to give you the time needed to reach a certain level of growth.
For instance, modeling growth exponentially as:
growth = etime
time can be determined using ln
as follows:
ln(growth)
