Brief Summary:
To develop TI pronounced T-sub-I a personal computer program to analyze time-varying data generated by periodic patient reports repeatedly-observed disease signs or serial biomarkers to study chronic disease
Detailed Description:
BACKGROUND
With the advent of quasi-likelihood generalized estimating equations and new ways to handle missing data has come a striking increase in applicable models perhaps more than after the 1972 introduction of the Cox model for survival data TI provided a way to analyze the data
DESIGN NARRATIVE
TIl provided graphics for data exploration and model validation TI ran under most current version of Windows used Civilized Softwares MLAB as its programming language offered context-sensitive help a dictionary of relevant terms identification of file entries from their screen position and simple animation TI permitted the user to analyze time-varying data from the two perspectives of repeated measured using a variety of models and time series where both time and frequency domain tools were provided
The study completion date listed in this record was obtained from the End Date entered in the Protocol Registration and Results System PRS record
