R Dataset / Package HSAUR / schizophrenia
On this Picostat.com statistics page, you will find information about the schizophrenia data set which pertains to Age of Onset of Schizophrenia Data . The schizophrenia data set is found in the HSAUR R package. Try to load the schizophrenia data set in R by issuing the following command at the console data("schizophrenia"). This may load the data into a variable called schizophrenia. If R says the schizophrenia data set is not found, you can try installing the package by issuing this command install.packages("HSAUR") and then attempt to reload the data with library("HSAUR") followed by data("schizophrenia"). Perhaps strangley, if R gives you no output after entering a command, it means the command succeeded. If it succeeded you can see the data by typing schizophrenia at the command-line which should display the entire dataset.
If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the schizophrenia R data set. The size of this file is about 2,719 bytes.
Age of Onset of Schizophrenia Data
Data on sex differences in the age of onset of schizophrenia.
A data frame with 251 observations on the following 2 variables.
A sex difference in the age of onset of schizophrenia was noted by Kraepelin (1919). Subsequently epidemiological studies of the disorder have consistently shown an earlier onset in men than in women. One model that has been suggested to explain this observed difference is know as the subtype model which postulates two type of schizophrenia, one characterised by early onset, typical symptoms and poor premorbid competence, and the other by late onset, atypical symptoms, and good premorbid competence. The early onset type is assumed to be largely a disorder of men and the late onset largely a disorder of women.
