Statistical analysis on AVO data

Amplitude versus offset (avo) interpretations involve a large volume of data. In order to carry out lithologic predictions, the avo data is reduced and simplified by various methods: avo gradients, zero offset amplitudes, even common mid point (cmp) stacks. All these displays are simplifications of a data set that may be influenced by several amplitude factors, such as lithology, tuning effects, correlated noise etc.
