GETARAIC {RSEIS} | R Documentation

## Auto-Regressive AIC estimate of arrival time

### Description

Auto-Regressive AIC for arrival estimate, signal detection

### Usage

    GETARAIC(z4, DT = 0.008, Mar = 8, O1 = 2, O2 = 0.2, WW = 2, T1 = 1, PLOT = FALSE)

### Arguments

`z4` | signal time series
`DT` | sample rate,s
`Mar` | AR Model Order
`O1` | window before, s
`O2` | window after, s
`WW` | window length, s
`T1` | initial guess, number of samples from beginning of trace
`PLOT` | logical, TRUE =plot

### Details

Method of Sleeman for automatic phase determination.

### Value

### Examples

    data(CE1)
    plot(CE1$x, CE1$y, type='l')

    Xamp = CE1$y[CE1$x>4.443754 & CE1$x<6.615951]
    Mar=8
    z4 = Xamp
    DT = CE1$dt
     T1 = 50

    O1 = 10*DT
    O2 =  10*DT
    WW = 10*DT
    Nz4 = length(z4)

     araict = GETARAIC(Xamp, DT=CE1$dt, Mar=8, T1=T1, O1=O1, O2=O2, WW=WW,   PLOT=TRUE)
