A data frame with 363 observations on the following 9 variables.

- y0
a numeric vector of the response simulated with one covariate for the nonparametric component under homoskedastic regression error assumption.

- y1
a numeric vector of the response simulated with one covariate for the nonparametric component under heteroskedastic regression error assumption.

- y2
a numeric vector the response simulated with two covariates for the nonparametric component under homoskedastic regression error assumption.

- x1
a factor with levels {

`F`

,`M`

}.- x2
a numeric vector of a covariate in the fixed parametric component.

- x3
a numeric vector of a covariate in the fixed parametric component.

- t1
a numeric vector of a covariate in the fixed nonparametric component.

- t2
a numeric vector of a covariate in the fixed nonparametric component.

- cluster
a clustering variable. There are 20 clusters. The cluster size is unbalanced; each cluster consists of from 5 to 30 observations.

Data are generated from the following three models:

*y0=β_0+β_1x1+β_2x2+β_3x3+γ_1(t1)+u+e_0**y1=β_0+β_1x1+β_2x2+β_3x3+γ_1(t1)+u+e_1**y2=β_0+β_1x1+β_2x2+β_3x3+γ_2(t1,t2)+u+e_1*where

*(β_0, β_1, β_2, β_3)=(1, 1, 0.5, -1)**γ_1(t1)=2sin(t1)**γ_2(t1, t2)=2sin(t1)+0.3t2+0.75t2^2**u \sim N(0,3)**e_0 \sim N(0,1)**e_1=x3*e_0*u is the cluster-specific random intercept. x2 and t1 are correlated with correlation coefficient about 0.67.
