NORMSINV (Probability)

• $Probability$ is the value of the Probability.
  • NORMSINV(),returns the inverse of the standard normal cumulative distribution.

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 $NORMSDIST(Number,Accuracy)=Probability$, then $NORMSINV(Probability)=Number$.
• $NORMSINV$ using the iterating method to find the value of $Number$.
• Suppose the iteration has not converged after 100 searches, then the function gives the error result.
• In $NORMSINV(Probability)$, where $Probability$ is the probability value of the Standard Normal Cumulative Distribution.
• This function will return the result as error when

1.Probability is non-numeric.
2.Probability<0 or Probability>1.

Examples

1. =NORMSINV(0.9999975333) = 4.567600
2. =NORMSINV(0.00241) = -2.818823592
3. =NORMSINV(1) = #N/A (PROBABILITY >0 (OR) PROBABILITY < 1)
4. =NORMSINV(0.00001) = -4.264890794
