Table 1.
Settings and parameter estimation results for the simulation study in Section 6. The first part of the table displays the true curves used in the model. The second part of the table displays the true value, the average estimates and the mean squared errors (MSE) of the parameters in the joint model. 
are the variances of 
and 
respectively. The number marked with an asterisk is the actual number multiplied by 
. The lower part of the table displays the rate of true null hypothesis for 4 methods with 
. PEN
represents the penalized likelihood with 
knots. UN
, UN
and UN
are the unpenalized likelihood methods with 
, 
and 
knots, respectively
