# Normal Distribution

Contents[Hide]

The Normal Distribution function calculates the standard normal distribution for an input data series.

Specifically, the function computes the relative likelihood that a continuous random variable would equal the input value if the series had a symmetrical "bell-curved" distribution.

The Normal Distribution Group function can be optionally used to calculate the standard normal distribution for each input data series grouped by the specified hierarchies.

## 1. Syntax

Normal distribution:

```NORMALDIST(d0,Alignments...)
```

Normal distribution group:

`NORMALDISTGROUP(d0,Alignments...)`

## 2. Input

The Normal Distribution function requires the following input series:

• d0 - Input data values - The set of data values for which the Normal Distribution is calculated.

## 3. Parameters

The Normal Distribution function requires the following parameters:

• Alignments... (One or More, Optional) – Hierarchy placeholders to be used as the alignment axis.

## 4. Output

The Normal Distribution function generates the following outputs:

• Normal Distribution - The Normal Distribution result set.

The Normal Distribution Group function generates the following outputs:

• Normal Distribution Group - The Normal Distribution Group result set.
