NORMSINV(prob)

• $prob$ 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 $NORMSDIST(x)=prob$, then $NORMSINV(prob)=x$.
• $NORMSINV$ 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 $NORMSINV(prob)$, where prob is the probability value of the standard normal cumulative distribution.
• This function will return the result as error when

1.prob is nonnumeric.
2.prob<0 or prob>1.

Examples

1. NORMSINV(0.9999975333)=4.567600
2. NORMSINV(0.00241)=-2.818823592
3. NORMSINV(1)=Null
4. NORMSINV(0.00001)=-4.264890794
