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

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