One recent study found that anti-infective agents, particularly antibiotics, increased the risk of schizophrenia (hazard rate
ratio, 2.05; 95% confidence interval, 1.77-2.38) and affective disorders (HRR, 2.59; 95% CI, 2.31-2.89), which the researchers attributed to brain inflammation, the microbiome, and environmental factors (Acta Psychiatr Scand.
where h(t, [X.sub.it]) is the hazard rate
function, and [h.sub.0](t) is the baseline hazard function, and [X.sub.it] is a vector of covariates.
The hazard rate
can be interpreted as the percentage of drivers who exited F1 at the end of a given season, given their level of tenure at time t.
Drawing on representative household-level data from Germany, Meng (2011) shows that when an employed women aged 58 or above is engaged in informal care giving, her hazard rate
of retirement is raised by a striking 74% in the subsequent year.
where the hazard function has constant, increasing, decreasing, bathtub, and upside-down bathtub hazard rate
The third approach provided the risk or hazard rate
of a nest surviving based on categorical covariates.
In survival analysis of time to death, or to any event, the hazard rate
is a measure of the risk in the population at large.
Given that we examine the probability that a subsidiary divestment will occur under the condition that all other subsidiaries are also at risk during the same time period, we employ a Cox proportional hazard rate
model as a commonly used statistical method in the event history analysis.
The hazard rate
of Double Weibull Distribution (DWD)
With this explanation in mind, we will now focus on articulating theory concerning the expected hazard rate
(likelihood) that motor carriers receiving warning flags at the start of the CSA program will come to exit this flagged status.
Of arguably more utility than the survivor function in EHA is the hazard function, or hazard rate
. The hazard rate
is defined as the rate in which the duration or event ends (i.e., the event has been experienced), given that the target event or the duration has not ended prior to that particular time interval (Box-Steffensmeier & Jones, 1997).
They develop the hazard rate
function which includes the following steps:
