  • Help on Weibull incidence analysis

    Hi,

    I am trying to do Weibull analysis on cancer onset.

    My data are respondents aged 51-79 and im interested in the disease incidence for different educational attainment.
    I am using 2 waves and created a dummy variable; cancer_disease_onset . If the respondent develops cancer in between the waves.

    stset agey_br, failure(cancer_disease_onset==1)
    streg agey_br male i.educ_group, dist(weibull)

    this result suggests that younger individuals are at higher risk of developing heart disease compared to older individuals. specifically for each additional year of age, the risk of developing heart disease decreases by about 95%??

    I dont understand this.

    Am i doing something wrong in the model or do i interpret this

    thanks in advance
