How do I have to write for example 4 mesured values of the same sample to
get them averaged?
This Way:
**************************************
BEGIN_DATA_FORMAT
SAMPLE_ID RGB_R RGB_G RGB_B XYZ_X XYZ_Y XYZ_Z
END_DATA_FORMAT
NUMBER_OF_SETS 4
BEGIN_DATA
1 47.376 7.6600 73.368 17.081 8.1277 47.746
2 47.376 7.6600 73.368 18.012 8.8732 48.382
3 47.376 7.6600 73.368 17.001 7.6789 47.134
4 47.376 7.6600 73.368 16.982 2.1987 32.712
END_DATA
**************************************
Or that way:
**************************************
BEGIN_DATA_FORMAT
SAMPLE_ID RGB_R RGB_G RGB_B XYZ_X XYZ_Y XYZ_Z XYZ_X XYZ_Y XYZ_Z XYZ_X XYZ_Y
XYZ_Z XYZ_X XYZ_Y XYZ_Z
END_DATA_FORMAT
NUMBER_OF_SETS 1
BEGIN_DATA
1 47.376 7.6600 73.368 17.081 8.1277 47.746 18.012 8.8732 48.382 17.001
7.6789 47.134 16.982 2.1987 32.712
END_DATA
**************************************
And how are they averaged? Value measured value Nr. 4 is obviously wrong. Do
you use the arithmetic mean, the median, or do you calculate a statistic
confidence interval to filter out outliers like value Nr.4
