Blood-type Scores

Reading Prof. Matsui's paper and Prof. Samamoto's paper, I think principal component analysis or discriminant function is suited for analyzing the data.  But I found no such papers -- till now.  Why?  So I'm going to try!
Please read textbooks of multiple variant analisys if you want to know more about it.

How to calculate

But I have no statistical software -- mmmh.  Finally I make up the numbers "blood-type scores" (these numbers correspond to discriminant functions if distribution of each blood types are the same).    "Blood-type scores" are such numbers that the characteristics of each blood type are applicable to specific blood types.  The higher the numbers are, the "likelier" the characteristics are.

The data of the first paper

Calculation is easy.  Calculate distances of each blood types from the average of four blood types.  Let's try the data of Prof. Matsui's paper first! I'll calculate "Type-O score" for example:

Calculate the average of four blood types using Table 2.   Then the difference between the average and Type O becomes "Type O coefficient". To caluculate "Type-O score" of the certain blood type, miltiply each values (difference from the average) and "Type-O coefficients", then sum up all the twenty questions.  After all, I get 378.50 for "Type-O score" of Type O itself.

How to Calculate "Type-O Score" of Type O Itself

Items	Type O	Type A	Type B	Type AB	Average	Type-O Coefficent	Type-O Score
1. I am particular with everything	55.5	53.3	47.1	55.9	52.95	2.55	6.50
2. I care about it to the person of the surroundings	57.1	63.1	58.7	61.8	60.18	-3.08	9.46

13. I am distant to people	33.5	40.4	41.3	45.6	40.20	-6.70	44.89

17. I am both romatic and realistic	80.8	80.4	81.2	94.1	84.13	-3.33	11.06
18. I care human relations, especially esteem trust of people	84.6	84.9	79.7	80.9	82.53	2.07	4.31
19. I have vitality	35.2	38.2	37.0	52.9	40.83	-5.63	31.64
20. I go straight with persistance and achieve when the purpose is decided	66.5	66.7	65.9	66.2	66.33	0.17	0.03
Total	-	-	-	-	-	-	378.50

That calculated about all the blood types with the same way, is the next table.

All "Blood-type Scores"  highest in red / lowest in blue

Blood Type	Type-O Score	Type-A Score	Type-B Score	Type-AB Score
Type O	378.50	9.53	7.46	-395.49
Type A	9.53	136.17	-54.97	-90.72
Type B	7.46	-54.97	175.01	-127.50
Type AB	-395.49	-90.72	127.50	613.72

The result is so evident.  Type AB shows the trend that differs and contrast in comparison with other blood types in this data.  Also, contrastive are pair of Type O and Type AB, and pair of Type A and Type B (except Type AB).

The data of the second paper

Let's try another data of Prof. Matsui's paper.
This time, calculate "Type-X coefficient" with the average of four years, then calculate all the blood types of each year and the average.

Blood-type Scores in 1980  highest in red / lowest in blue / consistent for four years in bold

Blood Type	Type-O Score	Type-A Score	Type-B Score	Type-AB Score
Type O	-0.08	10.60	-9.78	-0.74
Type A	-1.14	17.54	-17.36	0.96
Type B	-8.98	-30.67	56.35	-16.70
Type AB	10.20	2.52	-29.22	16.49

Blood-type Scores in 1982  highest in red / lowest in blue / consistent for four years in bold

Blood Type	Type-O Score	Type-A Score	Type-B Score	Type-AB Score
Type O	23.73	-11.47	-8.25	-4.01
Type A	-6.31	20.41	-18.33	4.24
Type B	-12.40	-15.29	42.83	-15.14
Type AB	-5.01	6.35	-16.25	14.91

Blood-type Scores in 1986  highest in red / lowest in blue / consistent for four years in bold

Blood Type	Type-O Score	Type-A Score	Type-B Score	Type-AB Score
Type O	10.99	-14.44	1.71	1.74
Type A	-17.46	56.62	-30.58	-8.58
Type B	-9.40	-19.18	40.92	-12.33
Type AB	15.87	-22.99	-12.04	19.16

Blood-type Scores in 1988  highest in red / lowest in blue / consistent for four years in bold

Blood Type	Type-O Score	Type-A Score	Type-B Score	Type-AB Score
Type O	22.08	-12.82	-9.55	0.29
Type A	-3.21	42.27	-34.11	-4.96
Type B	4.92	-35.24	34.23	-3.92
Type AB	-23.79	5.78	9.42	8.59

Blood-type Scores in Average  highest in red / lowest in blue / consistent for four years in bold

Blood Type	Type-O Score	Type-A Score	Type-B Score	Type-AB Score
Type O	14.18	-7.03	-6.47	-0.68
Type A	-7.03	34.21	-25.09	-2.09
Type B	-6.47	-25.09	43.58	-12.02
Type AB	-0.68	-2.09	-12.02	14.79

The result is so evident, too.  Type A and Type B show the clear constrast.  Also, contrastive are Type O and Type AB.  They are consistent for four years (but Type O and Type AB are not stable), as Mr. Nomi said.
