Aritmetic Mean Ar


This aggregation_operator calculate the aritmetic mean of the indices values. It is implemented as follow:

The alfa value is 1 and ai are the indices values for each amino acid.

Geometric Mean G


In ProtDCal this aggregation_operator is implemented as follows:

ProtDCal implement various options to process the harmonic mean, this are:

IGNORE THE "0" VALUES With this option with zero rates are excluded only operations, but not analysis, that is, zero elements are taken into account when dividing or find the nth root.
PRINT -9999 This option prints the value -9999 occurs when a mathematical uncertainty. In the case of the geometric mean would occur when the group size is zero, whereas in the case of the harmonic mean occurred when any of the elements is zero.
DELETE THE "0" VALUES With this option with zero rates are not scanned and not taken into account when dividing or find the nth root.

Harmonic Mean


This aggregation_operator calculates the armonic mean for the group.

Where alfa is equal to -1 and ai is the indice value for each amino acid. ProtDCal implement various options to process the harmonic mean, this are:

IGNORE THE "0" VALUES With this option with zero rates are excluded only operations, but not analysis, that is, zero elements are taken into account when dividing or find the nth root.
PRINT -9999 This option prints the value -9999 occurs when a mathematical uncertainty. In the case of the geometric mean would occur when the group size is zero, whereas in the case of the harmonic mean occurred when any of the elements is zero.
DELETE THE "0" VALUES With this option with zero rates are not scanned and not taken into account when dividing or find the nth root.

Squared Mean P2


This aggregation_operator calculate the squared mean for the group. It is implemented as follow:

The alfa value is 2 and ai are the indices values for each amino acid.

Cube Mean P3


This aggregation_operator calculate the cube mean for the group. It is implemented as follow:

The alfa value is 3 and ai are the indices values for each amino acid.
