ppsd.m %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% DESCRIPTION: PPSD makes power spectral density estimates of the time-series objects in the input analysis objects by estimating ARMA models coefficients. The coefficients are stored in the procinfo plist of the output objects. CALL: bs = ppsd(a1,a2,a3,...,pl) bs = ppsd(as,pl) bs = as.ppsd(pl) INPUTS: aN - input analysis objects as - input analysis objects array pl - input parameter list OUTPUTS: bs - array of analysis objects, one for each input Parameters Description %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

| Key | Default Value | Options | Description |
| METHOD | 'AR' |
|
Model type to use and estimate its coefficients. |
| ORDER | [] | none | Order of the applied filter. If the method chosen is 'ARMA', then a vector of 1x2 size must be provided containing the orders AR and MA models. (example: [ p q ]).
|
| TIMES | [] | none | The time range to analyze. If not empty, sets the time interval to operate on. |
| SPLIT | [] | none | The time range to analyze. If not empty, sets the timeinterval to operate on. As in ao/split, the interval can be specifiedby:
|
| SCALE | 'PSD' |
|
The scaling of output. Choose from:
