The F-test on all coefficients equals zero is overwhelmingly rejected.
We confirmed the proportional hazards assumption was met for the main exposure and other covariates by including interaction terms with time and using the Wald χ-procedure to test whether all coefficients equaled 0 (Ng'andu, 1997).
The model F test assumes that the fractions of missing information of all coefficients are equal (equal FMI) and thus rejects the hypothesis that all coefficients are equal to zero.
Considering identities (3.17) for and taking into account the fact that the left-hand side of (3.17) is, on every interval,, a polynomial in having only a finite number of zero points, we conclude that identity (3.17) is only true in the case of polynomials having all their coefficients equal to zero.
&Based on the Wald test of the null joint hypothesis of no association of the severity symptoms with adequate glycemic control (i.e. all coefficients are equal to zero).
Consistently, the last row (F test) shows that all specifications reject the null that states that all coefficients are equal to zero.
In particular, seven coefficients are statistically different from their counterparts in Column (2), and a Wald test of the hypothesis that all coefficients are equal to their counterparts in Column (2) clearly rejects (p-value in the table notes).
