The DNORM3P function returns the probability density that the value of a variable that
follows the normal distribution is equal to x.
Syntax
IDAX.DNORM3P(DOUBLE x, DOUBLE mean, DOUBLE stdev)
Parameter descriptions
- x
- Mandatory.
- The value that is to be computed.
- DNORM3P(x,mean,stdev)=exp(-((x-mean/stdev)^2/2)/sqrt(2*PI*stdev^2) for all x values.
- Data type: DOUBLE
- mean
- Mandatory.
- The mean value of the distribution.
- DNORM3P(x,mean,stdev)=exp(-((x-mean/stdev)^2/2)/sqrt(2*PI*stdev^2) for all mean values.
- Data type: DOUBLE
- stdev
- Mandatory.
- The standard deviation of the distribution.
- DNORM3P(x,mean,stdev)=exp(-((x-mean/stdev)^2/2)/sqrt(2*PI*stdev^2) for all positive stdev
values.
- If stdev is 0 or less, DNORM3P(x,mean,stdev) is null for all x values and mean values.
- Min: 0.00000000001
- Data type: DOUBLE
