Example

Only allows certain entries in a cell

Can use lists similar to Drop Down Boxes

Difficult to identify

Does not update automatically

Data validation

Useful Functions:

A subjective list

Evaluates a condition for TRUE or FALSE outcome and returns one specified value if the condition is TRUE and another specified value if the condition is FALSE

Evaluate a condition or multiple conditions allowing the model developer to specify what to return for both the TRUE and FALSE outcomes

The "value_if_true" and "value_if_false" can be expressions with functions themselves

The most common function for conducting conditional tests on values and formulae

IF

Performs addition of cells or an array of cells if a given criteria is satisfied.

Allows the model developer to specify what cells to add according to the condition satisfied

Combinations of the functions "IF" and "SUM" can be replaced by a single "SUMIF" function

SUMIF

Multiplies corresponding components in the given arrays, and returns the sum of those products.

Enables the user to avoid using complicated formulas by summing up the products of individual corresponding cells within the indicated arrays

Array arguments to be calculated must be of the same dimension

SUMPRODUCT

Example

LOOKUP

The LOOKUP function returns a value either from a one-row or one-column

range or from an array. The LOOKUP function has two syntax forms: the

vector form and the array form.

Use the vector form

when you have a large

list of values to look up

or when the values may

change over time

Use the array form

when you have a small

list of values and the

values remain constant

over time

Replace an

‘assumption’ with a

‘lookup’ or ‘choose’

Last row can be

copied down. All

assumptions in the

model could be in

this format….

Example

EOMONTH

Returns the serial number for the last day of the month that is the indicated

number of months before or after start date. Use this function to calculate

maturity dates or due dates that fall on the last day of the month.

Excel stores dates as serial

numbers so they can be

used in calculations

If start_date is not a valid

date, EOMONTH returns

the #NUM! error value

If start_date plus months

yields an invalid date,

EOMONTH returns the

#NUM! error value

Analysis Toolpak function

Example

Returns a value or the reference to a value from within a table or range.

Used to return either the value or reference of a cell within a range for a given row and column.

On its own, this function will always output the value of the referenced cell

Its output may be return either a value or cell reference, when nested within certain functions

INDEX

Returns the relative position of an item in an array that matches a specified value in a specified order.

MATCH returns the position of the item in the range, not the item itself
