Conditional survival function of T₂, given $t_1=0.1$ and given $t_1=2$; the conditional distribution of T₁ and T₂ given X = x is exponential with rate $\lambda e^{\beta x}$, λ = 1 and β = 1, and X has a normal distribution with mean 0 and standard deviation ${\sigma }^2$, with different values of σ.
