@prod |

Product.

Computes the product of the elements of x. Note that this function is prone to numeric overflow.

Syntax: @prod(x[, s])

x: series, vector, matrix

s: (optional) sample string or object when x is a series and assigning to a series

Return: number

For series calculations, EViews will use the current or specified workfile sample.

Examples

If x is a series of length 5 whose elements are 1, 2, 3, 4, 5, then

= @prod(x)

returns 120 (or equivalently, 5!).
