英格兰和威尔斯艾滋病报告的延迟数据


Description(描述)

    The aids data frame has 570 rows and 6 columns.
    该aids数据框具有570行和6列的数据.


    Although all cases of AIDS in England and Wales must be reported to the Communicable Disease Surveillance Centre, there is often a considerable delay between the time of diagnosis and the time that it is reported.
    尽管英格兰和威尔斯艾滋病的案例必须要向传染病监测中心汇报,但是经常会考虑诊断日期和报导日期之间的延迟。
     In estimating the prevalence of AIDS, account must be taken of the unknown number of cases which have been diagnosed but not reported.
    为了估计艾滋病的蔓延,必须记录那些已被诊断但还未被报导的艾滋病案例的数量。
    The data set here records the reported cases of AIDS diagnosed from July 1983 and until the end of 1992.
     该数据集记录了从1983年7月到1992年末的被诊断的艾滋病案例。
     The data are cross-classified by the date of diagnosis and the time delay in the reporting of the cases.
     该数据根据诊断日期和案例报导的延迟时间进行交叉分类。

This data frame contains the following columns: 
数据框包括以下列:

year(年)

   The year of the diagnosis.
   诊断的年份.
quarter(季度)

   The quarter of the year in which diagnosis was made.

   诊断时间和上报时间之间的延迟(月份)
   0 means that the case was reported within one month.
   0表示该案例的上报在一个月之内。
   Longer delays are grouped in 3 month intervals and the value of delay is the midpoint of the interval
