Popis:	Estimation of correlation between sensory and instrumental data for food products is used in research and industrial applications. Often the measurement techniques destroy the sample making it impossible to collect more data on the same item. This results in a correlation based not on individual observations but rather on the average of the data, leading to an erroneous and artificially high correlation. A method using maximum likelihood techniques and conditional simulation is proposed for estimating the correlation in this case.
