Appendix A (Variable coding)

Party Identification - Dummy variables for each party based on CPSK1
- (1 if specified party; imputed if CPSK1 = 98 or 99; 0 otherwise)

Feeling Thermometers – rescaled from 0 to 1; 996 = 0; imputed if 997, 998, 999
- Liberal (CPSD1H)
- Progressive Conservative (CPSD1G)
- NDP (CPSD1I)
- Reform (CPSD1J)
- Bloc Quebecois (CPSD1K)

Age 1997
– CPSAGE; 19 if CPSAGE = 9997; imputed if CPSAGE = 9999

French
  1 if CPSM14 = 1 or 12; imputed if CPSM14 = 98 or 99; 0 otherwise

Education
 0 if CPSM3 = 1 thru 4; 0.333 if CPSM3 = 5; 0.667 if CPSM3 = 6 thru 8; 1 if CPSM3 = 9 thru 11; imputed if CPSM3 = 98 or 99

Catholic
 1 if CPSM10 = 2; imputed if CPSM10 = 98 or 99; 0 otherwise

Religion Importance

 0 if PESM10B = 7; .333 if PESM10B = 5; .667 if PESM10B = 3;
 1 if PESM10B = 1; imputed if PESM10B = 8 or 9

Income

0 if = $30,000  (CPSM16 = 30 or CPSM16A = 2)
0.5  if > $30,000 and = $6,000  (CPSM16 > 30 and = 60) or (CPSM16A > 2 and = 5)
1  if > $60,000 (CPSM16 > 60 and = 997) or (CPSM16A > 5 and = 10)
Imputed if CPSM16 = 998 or 999 and CPSM16A = 98 or 99

Female
  if CPSRGEN = 5, 0 if CPSRGEN = 1

Campaign Interest
 Rescaled from 0 to 1 based on CPSB4, imputed if CPSB4 = 98 or 99

Knowledge of Parties
 Scale (from 0 to 1) based on PESE22, PESE23, PESE24, PESE29
 Each component = 1 if correct party only, 0.5 if correct party and another party, 0 if incorrect party or don’t know; imputed if = 9

Relative chance (Reform – PC)
Each party’s subjective chance of winning the riding was adjusted so that they summed to 1.0 .  This variable represents the signed difference between the adjusted subjective chance of the Reform candidate (based on CPSI1D) and the adjusted subjective chance of the Progressive Conservative candidate (based on CPSI1A).

Scale variables
(see cnes97r.txt for code detailing missing values of component variables which are imputed)

Sovereignty (Quebec only)
 Scale (from 0 to 1) based on CPSA2H, PESE10D, PESE10E, PESE21G

US
 Scale (from 0 to 1) based on PESE4, PESE25, PESF13

Liberal Performance
Scale (from 0 to 1) based on CPSF10A, CPSF10B, CPSF10C, CPSF10E, CPSF10F, CPSF10G

Quebec support (ROC only)
Scale (from 0 to 1) based on CPSE3A, CPSJ3, and PESF12

Free Enterprise (ROC only)
Scale (from 0 to 1) based on PESE19, PESE20, PESF1

Moral Traditionalism (ROC only)
Scale (from 0 to 1) based on CPSF2, CPSF3, and PESE5A
