Journal ArticleDOI
An autoregressive linear mixed effects model for the analysis of unequally spaced longitudinal data with dose-modification.
TL;DR: A state space form of the autoregressive linear mixed effects model is proposed to calculate the marginal likelihood without using large matrices so that the regression coefficients of the fixed effects can be concentrated out of the likelihood in this model.
Journal ArticleDOI
Dose-response relationship from longitudinal data with response-dependent dose modification using likelihood methods.
TL;DR: It is shown that maximum‐likelihood estimates are consistent without modeling the dose‐modification mechanisms when the selection of the dose as a time‐dependent covariate is based only on observed, but not on unobserved, responses, and measurements are generated based on administered doses.
Journal ArticleDOI
Analysis of covariance with pre-treatment measurements in randomized trials under the cases that covariances and post-treatment variances differ between groups
TL;DR: This paper considers non-normal data with unequal covariances and variances of post-treatment measurements, and examines the asymptotic properties of the ANCOVA with equal slopes using the variance estimated from a standard formula.
Journal ArticleDOI
Analysis of covariance with pre-treatment measurements in randomized trials: comparison of equal and unequal slopes.
TL;DR: This paper investigated the asymptotic properties of the ANCOVA with unequal slopes for post-treatment measurements with pre- treatment measurements as a covariate to compare two treatment groups.
Journal ArticleDOI
An Estimation Method of the Clearance for a One-Compartment Model of a Single Bolus Intravenous Injection by a Single Sampling
TL;DR: A method to estimate the clearance using a one-compartment model of a single-bolus intravenous injection from a single concentration at a sampling point between 1.5 and 2.5 half-lives is proposed.
