Using GAMMALN instead of GAMMALN.PRECISE
If you use the GAMMALN formula instead of GAMMALN.PRECISE, the result may be less accurate. Make sure to use the GAMMALN.PRECISE formula if you need high precision.
If the syntax of the GAMMALN.PRECISE formula is incorrect, it will return an error. Make sure to use the correct syntax: GAMMALN.PRECISE(value).
The following functions are similar to
GAMMALN.PRECISE or are often used with it in a formula:
GAMMALNfunction returns the natural logarithm of the absolute value of the Gamma function, Γ(x). The Gamma function is defined as an extension of the factorial function to complex and real numbers. The function is commonly used in probability theory and statistics to compute probabilities and to model continuous distributions such as the chi-squared and F distributions.
The GAMMA.DIST function calculates the gamma distribution probability for a specified x value, alpha and beta parameters. This function is often used in statistics to model continuous data that is skewed to the right. It can be used to analyze data in various fields such as finance, engineering, and social sciences.
GAMMA.INVformula returns the inverse of the cumulative distribution function for a specified probability and the Gamma distribution. It is commonly used in statistical analysis to find the value at which a specified percentage of the distribution lies. The Gamma distribution is a continuous probability distribution that is used to model the time until a certain number of events occur.
ERF.PRECISEfunction returns the error function integrated between the specified lower bound and upper bound.
The error function is used to calculate the probability of a value falling within a certain range of values.
