DATA_MIDDLEBROOKS1999 - Statistics about non-individualized HRTFs

Usage:

data = data_middlebrooks1999

Description:

data_middlebrooks1999 returns statistics summary from Fig. 13 (Middlebrooks, 1999b) showing the effect of non-individualized HRTFs.

Statistics of those parameters are stored as .mean and .quantiles representing the arithmetic mean and {0,5,25,50,75,95,100} quantiles, respectively.

The data struct comprises the following fields:

'le_own' local lateral RMS error (LE) when localizing with own HRTFs
'le_other' LE when localizing with others HRTFs
'lb_own' magnitude of lateral bias (LB) when localizing with own HRTFs; upper-rear quadrant excluded from analysis
'lb_other' LB when localizing with others HRTFs
'qe_own' quadrant error rate (QE) when localizing with own HRTFs
'qe_other' QE when localizing with others HRTFs
'pe_own' local polar RMS error (PE) when localizing with own HRTFs
'pe_other' PE when localizing with others HRTFs
'pb_own' magnitude of polar bias (PB) when localizing with own HRTFs; upper-rear quadrant excluded from analysis
'pb_other' PB when localizing with others HRTFs
