In rcssci: Visualization of Restricted Cubic Splines

rcs_quasipoisson.nshap

Description

restricted cubic splines (RCS) published in SCI.

Arguments

data	data.frame.Rdata
knot	knot=3-7 or automatic calculate by AIC min
y	outcome=0,1
covs	covariables, univariate analysis without "covs" command, multivariable analysis with "covs" command
prob	position parameter,range from 0-1
x	main exposure and X-axis when plotting
filepath	path of plots output.

Details

quasipoisson models with RCS splines were performed to explore the shape linear or nonlinear(U, inverted U,J,S,L,log,-log,temporary plateau shape)

Value

message.print PH assumption and other message
