Specifically, time-dependent sensitivity and specificity functions are defined as follows: s e n s i t i v i t y [ c, t | f (X ) ] = P r { f (X ) > c | δ (t ) = 1 }, s p e c i f i c i t y [ c, t | f (X ) ] = P r { f (X ) > c | δ (t ) = 0 }, in which c is the cut-off point, t is the survival time, f(X) are the prognostic indices, f (X ) = X ′ β and δ(t) is the event indicator at time t [ 16].
Furthermore, the probability of a negative response to pth indicator at time t conditional on latent health state j at time t is given by (4) The ρ quantities are known in the latent variable modeling literature as the item response probabilities, and they show precisely how the indicators (i.e., the diagnostic tests) measure the latent health states.
Assessment of model 2 shows that, after correction for the effects of disease characteristics and the socio-economic indicators at the time of diagnosis, a person's age at the time of diagnosis still relates to his current labour participation status.
The serum biochemical indicators (Tables 1, 2 and 3) demonstrated that liver, kidney and cardiac function in the three groups showed no significant changes (P > 0.05) at the different post-injection time points (1, 3 and 7 days).> -wrap-foot>> -wrap-foot>> -wrap-fooTheNote: The same indicators at different time points for pairwise comparisons (P > 0.05 for all of the comparisons).
This idea enables the decision making at process and product level taking into account different indicators at a time.
"We cannot rule out the possibility of sabotage, although the indicators at this time would not support that conclusion," Admiral Joshi said.
This idea enabled the decision making at process and product level taking into account the values of the different indicators at a time.
It doesn't guarantee safety through September, but these historical facts improve confidence in our bullish technical indicators at this time.
