NORMINV (Probability,Mean,StandardDeviation)
- is the probability corresponding to the Normal Distribution.
- is the Mean value.
- is the Standard Deviation.
- NORMINV(),returns the inverse of the normal cumulative distribution.
is the probability corresponding to the Normal Distribution.
is the Mean value.
is the Standard Deviation.
Description
- This function gives the inverse of the Normal Cumulative Distribution for the particular Mean and Standard Deviation.
- If , then .
- using the iterating method to find the value of a Number.
- Suppose the iteration has not converged after 100 searches, then the function gives the error result.
- In , where is the corresponding probability of the Normal Distribution, is the Arithmetic Mean of the Normal Distribution and is the Standard Deviation of the Normal Distribution.
- This function will return the result as error when
, then 
.
using the iterating method to find the value of a Number.
, where 1.any one of the argument is non-numeric 2.Suppose Probability<0 or Probability>1 3. StandardDeviation<=0.
- If Mean=0 and StandardDeviation=1, NORMINV uses the Standard Normal Distribution.
Examples
- =NORMINV(0.01884908749,17.4,3.2) = 10.750011
- =NORMINV(0.998742,5.4,2.3) = 12.349244172
- =NORMINV(1,7.2,2.3) = NULL
