With onboard consumables available for a 10 year mission and community resources accumulating, Kepler promises to continue invigorating stellar astrophysics with a large sample of high quality data obtained over a continuous baseline approaching the 11-year solar activity cycle.
Finally, we apply the proposed method to redesign the NINDS trial, which has been a source of controversy due to imbalance of continuous baseline covariates.
A specific continuous baseline hazard function is used to estimate mortality risk from survival times in the first model, whereas any function of time can be fitted to the mortality risk in the second model.
Motivated by potentially serious imbalances of continuous baseline covariates in clinical trials, we investigated the cost in statistical power of ignoring the balance of these covariates in treatment allocation design for a logistic regression model.
The associated features of photophobia, phonophobia, nausea, and vomiting, as well as the ipsilateral autonomic features of cluster are absent with the continuous baseline pain of HC.
HC is also distinguished from cluster headache and migraine by the presence of a continuous baseline headache that is usually unilateral and mild to moderate in severity.
For any continuous baseline G distribution, Zografos and Balakrishnan (Statistical Methodology 6 344 362, 2009) introduced the gamma-generated family of distributions with an extra shape parameter.
To check the balancing effect of propensity scores, we used the propensity scores as covariates in an analysis of covariance for continuous baseline variables and in multinomial logistic regression for categorical baseline variables.
To compare continuous baseline data between the cohorts, non-parametric Kruskal-Wallis ANOVA was performed, followed by Mann-Whitney U-test.
Continuous baseline data are expressed as means ± SD.
For the FPG analysis, continuous baseline FPG was also included in the general model.
