IDAX.PLNORM - Cumulative log-normal distribution

The PLNORM function returns the probability that the value of a variable that follows the log-normal distribution is smaller or equal to x.

Syntax

IDAX.PLNORM(DOUBLE x, DOUBLE medlog, DOUBLE sdlog

Parameter descriptions

x
Mandatory.
The value that is to be computed.
If x is 0 or less, PLNORM(x,medlog,sdlog) is null for all medlog values.
Min: 0.000000001
Data type: DOUBLE
medlog
Mandatory.
The median value on the logarithmic scale.
Data type: DOUBLE
sdlog
Mandatory.
The shape value on the logarithmic scale.
If sdlog is 0 or less, PLNORM(x,medlog,sdlog) is null for all medlog values.
Min: 0.000000001
Data type: DOUBLE
