plot_shhr

An object of class <code>mixpch</code>, resembling the survival function in treatment group 0

An object of class <code>mixpch</code>, resembling the survival function in treatment group 1

main

A maximum value for the x-axis. The plot is drawn using xlim = c(0, xmax)

xmax

A maximum value for the y-axis for the hazards plot. The plot is drawn using ylim = c(0, ymax_haz)

ymax_haz

A maximum value for the y-axis for the hazards ratio plot. The plot is drawn using ylim = c(0, ymax_hr)

ymax_hr

A convenience function that uses the generic plot function in the nph package to
plot the three functions in a layout of 3 columns and 1 row.

Piecewise constant hazard functions are used to flexibly model survival distributions with non-proportional hazards and
to simulate data from the specified distributions. Also, a function to calculate weighted log-rank tests for the
comparison of two hazard functions is included. Finally, a function to calculate a test using the maximum of a set of
test statistics from weighted log-rank tests is provided. This test utilizes the asymptotic multivariate normal joint distribution
of the separate test statistics. The correlation is estimated from the data.

plot_shhr: Plot of survival, hazard and hazard ratio of two groups as a function of time
