1. A computer-implemented method of determining a correlation of a logging parameter of a volume of a formation to a volume parameter of the volume of the formation, comprising: selecting, using a computer, a set of data points including the logging parameter at a plurality of depths over a depth interval in the formation and a volume parameter of the volume at the plurality of depths; relating the volume parameter to the logging parameter at each of the plurality of depths; for values of the logging parameter within a selected interval, estimating, using the computer, a standard deviation of the volume parameter and a standard deviation for the logging parameter; using the estimated standard deviations to obtain, using the computer, a plurality of sets of randomized data points; obtaining, using the computer, regression curves for each of the plurality of sets of randomized data points; determining, using the computer, the uncertainties of the logging parameter in the volume from the plurality of regression curves; determining, using the computer, a representation of the logging parameter of the formation in the volume from the volume parameter and the uncertainties of the logging parameter associated with the volume parameter; and performing a drilling operation in the volume using the representation of the logging parameter of the formation in the volume.
