NORMSINV(prob)
- prob is the probability value.
Description
- This function gives the inverse of the Standard Normal Cumulative Distribution.
- In Normal Distribution formula, when the Mean is zero and the Standard Deviation is 1 then it is called Standard Normal Distribution.
- If , then .
- using the iterating method to find the value of x.
- Suppose the iteration has not converged after 100 searches, then the function gives the error result.
- In , where prob is the probability value of the standard normal cumulative distribution.
- This function will return the result as error when
1. is non-numeric. 2. or .
Examples
- NORMSINV(0.9999975333)=4.567600
- NORMSINV(0.00241)=-2.818823592
- NORMSINV(1)=Null
- NORMSINV(0.00001)=-4.264890794
