lognormdist

Description: Returns the cumulative lognormal distribution of x, where ln(x) is normally distributed with a specified mean and standard deviation. Use this function to analyze data that has been logarithmically transformed.

Syntax: lognormdist(x, Mean, Standard_dev, Cumulative)

• x is the value at which to evaluate the function.

• Mean is the mean of ln(x).

• Standard_dev is the standard deviation of ln(x).

• Cumulative is a logical value that indicates which form of the exponential function to provide. If Cumulative is TRUE, lognormdist returns the cumulative distribution function; if FALSE, it returns the probability density function.

Remarks:

• Arguments must be numerical.

• x and Standard_dev must be > 0.

• The equation for the lognormal cumulative distribution function is:

• The equation for the probability density function is:

• All parameter values can include:

Example:

• lognormdist(4,3.5,1.2,TRUE)

Returns:

• 0.039084
