NORMINV(prob,m,sd)


  • is the probability corresponding to the Normal Distribution, is the Mean, and 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 x.
  • 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
1.any one of the argument is non-numeric
2.Suppose  or 
3..
  • If and , NORMINV uses the standard normal distribution.

Examples

  1. =NORMINV(0.01884908749,17.4,3.2) = 10.750011
  2. =NORMINV(0.998742,5.4,2.3) = 12.349244172
  3. =NORMINV(1,7.2,2.3) = NULL
