The coefficients α, α 1875 and α, α 1900 are not individually significant and the p-test p-values are statistically statistical in all years after treatment (1850, 1875 and 1900 ) Meaning a combined meaning. It is different from the date before 1850 (significance level is 5%). The second row of 15 repeats the same analysis without weighting the population. Although the results are similar in quality, weak, negative prestress is decreasing, but the coefficients related to 1875 and 1900 are no longer shared. It also includes the area on the east side of Elbe in the control area as described in the 3rd and 4th columns. This will improve baseline results in both weighted cases and unweighted cases. In column 3, the size of the coefficient is very similar to the size of the restricted sample in column 1. The joint significance of the F test on the effect of the year after treatment came to dismiss 2% invalidity
