melanoma Melanoma skin cancer incidence

Description

These data from the Connecticut Tumor Registry present age-adjusted numbers of melanoma skin-cancer incidences per 100,000 people in Connectict for the years from 1936 to 1972.

Usage

melanoma

Format

A data frame with 37 observations on the following 2 variables.

year

Years 1936 to 1972.

incidence

Rate of melanoma cancer per 100,000 population.

Note

This dataset is not related to the melanoma dataset in the boot package with the same name.

The S-PLUS 6.2 help for the melanoma data says that the incidence rate is per million, but this is not consistent with data found at the National Cancer Institute (https://www.cancer.gov/).
