This one month lag means that if you receive a 1099 you know is wrong, there may be time to correct it before the IRS receives a copy.
Disease notifications positively correlated at a lag of one month (lag 1) with search term frequency for 12 of the 17 diseases that exhibited significant Spearman's rank correlations.
A one month lag minimum temperature was the main splitter, with temperature below 14.05°C being associated with the lowest Anopheles density (mean: 1.6/house).
Thus there is a one-month lag between the time in situ concrete is poured and the time it can carry loads, which can significantly affect construction schedules.
NDVI values over the same period (2007 to 2012) indicate that when rainfall levels increase, forage levels ('greenness') also increase but with a one-month lag.
Figure 6 Livestock productivity, as measured by milk yields, correlates with a one-month lag in NDVI values (R 2 = 0.65, p < 0.05).
In terms of the optimal lead/lag, STING comes closest to being a contemporaneous indicator with a one-month lag (the OECD CLI attains its maximum contemporaneously, but the AUC is much lower), followed by FEDEA (which attains its maximum with a one-quarter lag) and finishing with MICA-BBVA (with a 5-month lag at which point its AUC is virtually identical to STING's).
The density of An. arabiensis was significantly associated with a one-month lag of rainfall in collections from CDC light traps (r = 0.81, P < 0.001), PSCs (r = 0.79, P = 0.002), and pit shelters (r = 0.63, P = 0.03).
The use of the one-month lag between visits to define new cases in our study also ensured sufficient number of events to improve the study efficiency, and decrease the possibility of counting follow-up visits as new events.
One-month lag has also been reported by a study that evaluated average temperatures over a monthly period across several whole years (Chang et al. 2004), but it was not clear whether the effects would have been more immediate if daily data had been evaluated.
A one-month lag of rainfall was significantly associated with the monthly EIR (r = 0.74, P = 0.006) of An. arabiensis from CDC light traps, but there was no significant association with the month of collection or with a two-month lag of rainfall (P > 0.05).
