Calculates the weighted average crude risk against the average exposure level for a continuous exposure. Each point corresponds to overlapping subgroups of 20 percent of the sample ordered from lowest to highest exposure and a sliding window of 1

formula specifying the binary outcome and the continuous covariate of interest, e.g. y~x

The crude.risk function is intended to explore the possible functional relationship between risk and exposure in a non-parametric way.
crude.risk
risk.exposure.plot
data(aarp) risk <- crude.risk(bladder70~redmeat, weights = aarp$w, data = aarp) risk.exposure.plot(risk, xlab = "Avg. Red Meat Consumption")
