#### 18.2 Normalizing

The option file changer function Normalizing offers the possibility to normalize your
data by applying a minimum-maximum-normalization method. The function
transforms all values to a new defined range e.g. 0 to 1000. Each value is subtracted
by the minimum value and devided by the difference of the range of all values.
The new values are then multiplied by the defined range according to the
formula:

| (3) |

Inverse Min-Max-Normalization additionally inverts all values by subtracting it
from the normalized range as in the following formula:

| (4) |

The inverse normalization is especially useful indicators are combined
within an index and single indicators are negative indicators while others are
positive.

Open the function settings dialog by double-clicking at the Option icon at the file
tree.

The Normalization function has the following dependencies:

##### 18.2.1 The Normalizing Settings Dialog

In the normalizing settings dialog select the range at which you want your data to be
standardized, e.g. between 0 and 100, betwen 0 and 1000 etc. Optionally select
inverse nomalization. Inverse Min-Max-Normalization additionally inverts all values
by subtracting it from the normalized range.
