Directions

1 Find the syntax of BetaDist. It is BetaDist (x,alpha,beta,A,B) where x is the value on which to evaluate the function, alpha is the alpha parameter of the beta distribution and beta yous the beta parameter about the beta distribution. Parameters A and B are optional and will be explained with Stage 2.

2 Include Some as the lower destined to x and B seeing that the upper bound to x when a non-normal cumulative beta distribution is desired. Otherwise, BetaDist will utilize the standard cumulative beta distribution where A=0 and B=1.

3 Review the way BetaDist works. BetaDist returns the fraction given by means of Bx(a,b)/B(a,b) where Bx(a,b) is the unfinished beta function also B(some,b) is the regularized unfinished beta function.

4 Observe the error conditions of BetaDist. BetaDist will return the #Value! blunder worth if any argument is non-numeric. BetaDist will return the #Num! mistake value if alpha

5 Look at an illustration of BetaDist.

=BetaDist(2,8,10,1,3) returns 0.685470581. hcg.

0.685470581 is the worth at which to evaluate the beta distribution. 8 is the alpha parameter of the beta distribution. 10 yous the beta parameter of the beta distribution. 1 yous the reduced bound of x. 3 is the upper destined of x.
