LOGINV function

PRO

The LOGINV function in Jspreadsheet Formulas Pro is a tool that gives you the inverse of the lognormal cumulative distribution function, using a specific mean and standard deviation. In simpler terms, this function helps you predict the possibility of a certain outcome based on a set of known data. This is useful when you're dealing with issues of probability, where it's necessary to analyze the likelihood of various outcomes. It's especially handy in financial analysis, quality control, and risk management scenarios.

Documentation

Returns the inverse of the lognormal cumulative distribution function with a specified mean and standard deviation.

Syntax

LOGINV(probability, mean, standard_dev)

Parameter	Description
`probability`	The probability for which you want to find the corresponding inverse of the lognormal cumulative distribution function.
`mean`	The mean of ln(x), where x is normally distributed. Can be any real number.
`standard_dev`	The standard deviation of ln(x), where x is normally distributed. Must be positive.

Behavior

The LOGINV function is used to return the inverse of the lognormal distribution. It requires three parameters: probability, mean, and standard deviation. The function expects numerical values for all these parameters.

If empty cells are used as arguments, they are considered as zeros.
Texts, booleans, or non-numeric values used as arguments will cause the function to return a #VALUE! error.
If any of the arguments are negative, the function will return a #NUM! error.
The function handles errors propagated from other cells. If any of the input cells contain an error, the LOGINV function will also return the same error.
If the probability is less than or equal to 0 or greater than or equal to 1, the function will return a #N/A error.

Common Errors

Error	Description
#VALUE!	This error occurs when any of the arguments to the function are non-numeric. This includes boolean values, text, or any other non-numeric data type.
#NUM!	This error is returned when any of the arguments are negative, as the lognormal distribution is undefined for negative values.
#N/A	This error is returned when the given probability is less than 0 or greater than 1.

Best practices

Always ensure that the arguments provided to the LOGINV function are numeric. Non-numeric values, including text and boolean values, will cause the function to return a #VALUE! error.

Be careful with the values you provide for the probability argument. It must be strictly between 0 and 1. Providing a probability value outside this range will result in a #N/A error.

Avoid using cell references that might contain negative values as the LOGINV function does not work with negative values, and it will return a #NUM! error.

Use error-checking functions like IFERROR or ISNUMBER to handle potential errors, especially when dealing with data that might contain non-numeric values.

Usage

A few examples using the LOGINV function.

LOGINV(0.5, 1, 1)  
// Returns approximately 2.718281828, the median of a lognormal distribution with mean=1 and std_dev=1.
LOGINV(0.9, 0, 0.25)  
// Returns approximately 1.377662044, representing the 90th percentile for a lognormal distribution with mean=0 and std_dev=0.25.
LOGINV(0.05, 0.5, 0.1)  
// Returns approximately 1.398660003, representing the 5th percentile for a distribution with mean=0.5 and std_dev=0.1.
