Document Summary
3 determinants of statistical significance: p -value (p < 0. 05) can reject the null, 95% confidence interval. Overlaps 0 cannot reject the null. Does not include zero will reject the null: standard error. Multiply standard error by 2 (critical value) Coefficient is statistically significant at the p < 0. 05 level. Need to distinguish beta coefficient estimate from 0 value (after 2*se) Is statistically significant at the 95% confidence level because . Zero is not in the 95% confidence interval; or. The regression coefficient is more than twice the standard error; or. Theory hypotheses measures and data testing and evaluating hypotheses. Fewer parties are capable of winning" parliamentary seats. Maximizing votes means staking out popular positions. There are strict limits to the viable policy space for competition. Ex. the expectation to see competitive parties cluster around the mean or median voter position. Parties can afford to be less concerned about. Whether they are occupying moderate, vote-maximizing positions.
