## stdise

Standardise tseries data by subtracting mean and dividing by std deviation

#### Syntax

    [X,M,S] = stdise(X)
    [X,M,S] = stdise(X,Flag)

#### Input arguments

- `X` [ tseries ] - Input tseries object whose data will be normalised.

- `Flag` [ 0 | 1 ] - `flag==0` normalises by N-1, `flag==1` normalises by `N`, where `N` is the sample length.

#### Output arguments

- `X` [ tseries ] - Output tseries object with standardised data.

- `XMeam` [ numeric ] - Estimated mean subtracted from the input tseries observations.

- `XStd` [ numeric ] - Estimated std deviation by which the input tseries observations have been divided.
