Standard deviation is greater than the mean value for Articles abroad Reviews and bibliographies Internal original reports Routine reports which indicates large dispersion in the data Skewness is positive for all the variables, indicating a long tail on the right of the mean. Peakedness of the distribution is high: highest for Internal Original Reports. The frequency distribution is highly Leptokurtic.

### 3(2) Example of Quantile Programme

 Research Question : What is the extent of inequality in the research output of scientists in India? (Note: Research output is measured by two variables: V363: # of Articles published in the Indian journals; V365: # of Articles published in foreign journals).

Gini coefficient = .739

##### INTERPRETATION
 IDAMS reports that 962 cases were read out of which 831 cases were taken for further analysis the remaining cases were deleted due to missing data. Cumulative distribution of articles in 25 classes. Minimum # of Articles = 0 and Maximum # of Articles = 40 Lorenz Curve: The area between the equidistribution line and the Lorenz curve indicates the inequality in the output of articles published in Indian journals. The value of Gini coefficient = 0.495. It may be noted that the maximum value of Gini coefficient is 1.000. Similar analysis was performed for articles published abroad. However the computer output is not shown. The value of Gini coefficient for articles published in foreign journals is 0.739. This value is much higher than that for articles published in Indian journals. These results imply that there is greater inequality in the distribution of articles published abroad, compared with that of articles published in the country.

### 3(3) Example of Rank Programmes

##### INTERPRETATION

IDAMS lists the cases containing illegal code or no valid answers. 294 such cases are identified. Out of 980 cases, 686 cases (980-294) are processed for analysis.

Input relational matrix. This is a matrix of fuzzy relations among the set of alternatives. The cells of this matrix indicate the dominance of one alternative over another. For example, the cell (Column 1, Row 2) indicates that the dominance of Alternative 1 over Alternative 2 is 0.4052, whereas the dominance of Alternative 2 over Alternative 1 is 0.4038.

In this matrix the values of only seven cells exceed the threshold of simple majority, which means that only a few preferences are expressed in a very clear manner. This is confirmed by the index of cohesion, 0.3892, which seems to be low. However, this index is not poor, when we take into account the small number of alternatives cited (3 out of 7).

Intensity = 0.5896. This index can be interpreted as the average credibility of the proposition "Alternative I is preferred to Alternative J" or "Alternative J is preferred to Alternative I"

Absolute dominance = 0.2295. This index indicates the average difference between the credibilities of the proposition "Alternative I is preferred to Alternative j" and of the opposite proposition "Alternative J is preferred to Alternative I".

Fuzzy Method – 1 (Non-dominated layers)

The cases are presented sequentially from the highest rank and for each of them, the following information is given:

• Its sequential number, with the certainty level,
• The code of the alternatives or the variable’s number,
• The membership function value of the alternative, indicating how strongly they are connected to the core. The membership values of alternatives, belonging to the previous cores are substituted by asterisks.
• List of alternatives, belonging to the core with the highest membership value (most credible alternatives).

3 > 6 > 1 > 2 > 4 > 7

Normalized Relational Matrix

It can be easily seen that the sum of the cell (1, 2) and cell (2, 1)

0.5009 + 0.4991 = 1.00

Cell( 1, 2) Cell (2, 1)

Fuzzy sets of Alternatives by rank:

All alternatives are listed sequentially with the following information:

• The code of the alternative, or the variable’s number,
• The membership function value of the alternative indicating how strongly it is connected to each rank,
• The list of most credible rank(s) for that alternative.

Degree of credibility of places of Alternative:
Rank 2 (Membership Value = .50090)
Degree of credibility of places of Alternative 3
Rank 1 (Membership Value = .50090)
and so on.

We get the following results:

 Alternative Rank 6 2 3 1 1 4 4 5 2 3 5 6 7 7

3 > 6 > 2 > 1 > 4 > 5 > 7

Fuzzy subsets of ranks by alternatives

• The rank’s number,
• The membership function value of the alternative indicating how strongly it is connected to each rank,
• The list of most credible alternative(s) for that rank.

Rank 1: Alternative with the highest membership value (.50090) is: 3
Rank 2: Alternative with the highest membership value (.50090) is: 6
and so on.

We get the following results:

 Rank Alternative 1 3 2 6 3 2 4 1 5 4 6 5 7 7

Thus the rank order is:

3 > 6 > 2 > 1 > 4 > 5 > 7
