rvmmat_est: NULL model estimation

In ZWang-Lab/RVMMAT: Retrospective Varying Coefficient Mixed Model Association Test

NULL model estimation

Description

This function estimate the parameters and residuals for the NULL model in RVMMAT

Usage

rvmmat_est(
  y.long,
  time,
  y.cov,
  phe.model = phe.model,
  maxiter = 50,
  tol = 10^(-6),
  Hd = 2,
  VCcorrection = FALSE
)

Arguments

y.long	Long-formatted phenotype vector
time	Time covarites matched with phenotype vector
y.cov	Covariate matrix denoting the covariate variables measured at each time
phe.model	String, the phenotype model, two optional values: 'logistic', 'Gaussian'
maxiter	Numeric, the maximum count for the iterative estimation in when using mixture correlation structure
tol	Numeric, tolerance for the iterative estimation in when using mixture correlation structure
Hd	Numeric, degree of derivative of smooth function which lead to smooth spline of order 2Hd
VCcorrection	Logical variable, indicating whether apply correction for variance components and natural parameters

Value

This function returns a list object with model parameters and residuals of the NULL model
