that Lin Zhijian handed over to Yu Zhenghuang at that time was processed information. In the part of the approval rate, only Lin Zhijian's data in the polls was left, but Cai Renjian, Xu Mingcai, and unspoken support were given. The rate was summed up, and it was given to Yu Zhenghuang after it became "unsupported or unspoken".
Because of this, the data obtained by phone database Yu Zhenghuang is only Lin Zhijian's support rate, and the rest is that he does not support or has not expressed his position. He can't see the respective support rates of Cai Renjian and Xu Mingcai. For comparison, Yu Zhenghuang was unable to make more horizontal comparisons (pages 40 and 63 of the paper). exb1 Author provided The only three-person comparison data provided is only the parameter "who can bring changes to Hsinchu" (page 50 of the paper), which limits Yu Zhenghuang's research results.
Therefore, we will see that in Yu Zhenghuang's research, most of the research methods that appear are "Comparing Lin Zhijian himself with himself", for example, on page 55, the way to prove that Lin Zhijian is more supported by young voters is to show support for Lin Zhijian by age group. Among voters, the proportion of younger voters is higher than that of older voters, but it is impossible to compare the supporters of Xu Mingcai and Cai Renjian at the same time, whether there is a similar trend.
