BETADIST
The BETADIST function in Google Sheets is a statistical function used to calculate the cumulative beta distribution for a given value. It is commonly used in hypothesis testing and in determining probability values for beta distributions. Learn how to use this function effectively with our comprehensive guide.
Function Syntax and Parameters
Syntax: BETADIST(value, alpha, beta, lower_bound, upper_bound)
Parameters:
value: The value at which you want to evaluate the distribution.alpha: The alpha parameter of the beta distribution.beta: The beta parameter of the beta distribution.lower_bound: The lower bound of the distribution.upper_bound: The upper bound of the distribution.
