Constructor Detail

Baker07_ImCorrRel

public Baker07_ImCorrRel()

no-argument constructor. All this does is set ti to Double.NaN (as the default)

Method Detail

getImCorrelation

public double getImCorrelation()

Computes the correlation coefficient between PGA and Sa at period Ti.

Specified by:

getImCorrelation in class ImCorrelationRelationship

Parameters:

ti, - spectral period in seconds

Returns:

pearson correlation coefficient between lnPGA and lnSa(Ti)

initOtherParams

protected void initOtherParams()

Creates other Parameters such as the tectonic region (and possibly others)

Overrides:

initOtherParams in class ImCorrelationRelationship

initSupportedIntensityMeasureParams

protected void initSupportedIntensityMeasureParams()

Creates the supported IM parameters (SA and PGA), as well as the independenParameters of SA (periodParam and dampingParam) and adds them to the supportedIMParams list. Makes the parameters noneditable.
