Normcdf
Normcdf-func
Description
Cmputes the probabilities of the specified tail type tail in a given value x, associated with a normal cumulative distribution.
Syntax
double prob = normcdf(double x,[int tail])
Parameters
x
- Input, the value of the standard Normal variate
tail
-
Input, Optional. The tail probability type using for the normal distribution
- 1 = the upper tail probability
- 2 = the lower tail probability (Default if not set)
- 3 = the two tail (significance level) probability
- 4 = the two tail (confidence interval) probability
prob
- Output, the returned probability.
Example
normcdf(9.9,3)=; // ANS: 4.1627504389865E-23
