# NTNORMDIST

Returns the standard normal distribution for the specified parameters.

## Syntax

NTNORMDIST(

• x,
• Cumulative

)

#### Parameters

• x is the value for which you want the distribution $(x>0)$.
• Cumulative is a logical value that determines the form of the function. If cumulative is TRUE, NTNORMDIST returns the cumulative distribution function; if FALSE, it returns the probability mass function.

## Remarks

• When argument Cumulative=TRUE, this function returns same result as Excel function “NORMSDIST” does.
• When argument Cumulative=FALSE, this function returns same result as Excel function “NORMSDIST(x,0,1,FALSE)” does.

## Example

• The example may be easier to understand if you copy it to a blank worksheet
