# Results memo — association between y and x (monthly, 1990-01 to 2023-04) Prepared by the previous analyst. Method: ordinary least squares of y on x with an intercept, using all 400 monthly observations in `series.csv`. Standard errors are the conventional OLS standard errors (independent, homoskedastic errors). | quantity | value | |---|---| | intercept | 2.0925 | | slope on x | 0.1017 | | standard error of the slope | 0.0448 | | t-statistic | 2.27 | | p-value (two-sided) | 0.0238 | | observations | 400 | Conclusion of the memo: the slope is statistically significant at the 5% level, so x is a significant predictor of y.
