In Colossus: "Risk Model Regression and Analysis with Complex Non-Linear Models"

uses a table, list of categories, list of summaries, list of events, and person-year information to generate person-time tables

Description

Event_Time_Gen generates event-time tables

Usage

Event_Time_Gen(table, pyr, categ, summaries, events, verbose = FALSE)

Arguments

table	dataframe with every category/event column needed
pyr	list with entry and exit lists, containing day/month/year columns in the table
categ	list with category columns and methods, methods can be either strings or lists of boundaries, includes a time category or entry/exit are both required for the pyr list
summaries	list of columns to summarize, supports counts, means, and weighted means by person-year and renaming the summary column
events	list of events or interests, checks if events are within each time interval
verbose	integer valued 0-4 controlling what information is printed to the terminal. Each level includes the lower levels. 0: silent, 1: errors printed, 2: warnings printed, 3: notes printed, 4: debug information printed. Errors are situations that stop the regression, warnings are situations that assume default values that the user might not have intended, notes provide information on regression progress, and debug prints out C++ progress and intermediate results. The default level is 2 and True/False is converted to 3/0.

Value

returns a grouped table and a list of category boundaries used
