Informative censoring may result in an imbalance of exposure time and a compromised ability to accrue clinically relevant or valid information regarding the primary clinical study outcomes (15).
The observational studies could not adjust for time dependent imbalance of severity: timing of return of spontaneous circulation is a determinant of both outcome and treatment (those who rapidly respond to initial resuscitation procedures would have a higher chance of survival and a lower chance of being given of adrenaline).
Moreover, there was no obvious imbalance of follow up time (person years) by year of taking the course, suggesting that any possible bias from specific cohort year was limited in the study.
Bullying is a broad construct that is manifested by deliberate antagonistic behavior by the bully towards the victim, persistence of this behavior over a period of time, and an imbalance of power between the bully and the victim [ 4- 8].
The evaluations will not consider a nation's reserves of foreign currency, but only the balance of imports and exports, a more narrow measure that does not reflect the accumulation of an imbalance over time.
The real-time imbalance of the wind farm was used as an input for this agent.
The difference between ( WP_{i} (t ) ) and WP i h,D is the imbalance of the wind farm at time t because of wind power fluctuation, where h ≤ t < h + 1: Delta,WP_{i} (t) = WP_{i} (t) - WP_{i}^{h,D} (3 If ΔWP i (t) < 0, it indicates that the power output of the wind farm at time t is less than the scheduled value in the day-ahead market, which needs to be compensated by up regulation.
Fortunately, the scientific method is designed to correct for that kind of imbalance, given sufficient time and opportunity.
They have suffered plenty of times in this competition but has there ever been a time when the imbalance of talent has felt so extreme and they have been so grateful to be spared an even more harrowing ordeal?
In my research, I spent an enormous amount of time examining data on opportunity costs, gender imbalance, family policy, time use, personality traits and so on.
