Name
maok — k-periods uncentered moving average for a matrix
CALLING SEQUENCE
xma = maok(x,k)
PARAMETERS
- Input
x = a (n x l) matrix
k = size of the moving average
- Output
xma = the filtered matrix (with the same size of x)
DESCRIPTION
Computes k-periods uncentered moving average. The first (k-1)-values of the moving average are compute by "pading" the first initial values of the time serie.
EXAMPLE
x= grand(200,1,'nor',0,1);
xma = maok(x,12)
