Uncertainty rate – Self-reported exposure to robbery, percentage (%)

This is an uncertainty number, for more information see Unsafe data on kolada.se. “Self-reported exposure to robbery, percentage (%)” is an excise estimate from a sample survey. This means that the estimate is not necessarily representative of the population as a whole. However, with the point estimate ± the uncertainty number, one can most likely say that the true mean is within the range. Brå uses asymmetric confidence intervals, in Kolada the uncertainty number is given as the maximum distance between the confidence interval and the point estimate. This means that the point estimate ± uncertainty may differ in one direction to the confidence interval from the NTU. For example, 2019-2020 is merged and published for the last year, such as the year 2020 in Kolada, the results for 2021 and 2022 are merged and the joint result will be published in the year 2022 in Kolada.本数值为不确定度数值，如需获取更多信息，请参阅kolada.se网站上的「不安全数据（Unsafe data）」板块。「自我报告的抢劫受害占比（%）（Self-reported exposure to robbery, percentage (%)）」为抽样调查得到的估计量，这意味着该估计值未必能完全代表整体总体的情况。不过，通过点估计值±不确定度数值，我们可以大概率认定真实均值处于该区间范围内。Brå采用非对称置信区间，而在Kolada平台中，不确定度数值被定义为置信区间与点估计值之间的最大距离。这意味着点估计值与不确定度构成的区间，在单侧方向上可能与NTU给出的置信区间存在差异。例如，2019-2020年的数据会合并后以最后一年的名义发布，如在Kolada平台中以2020年的名义发布；2021年与2022年的数据将合并，并于2022年在Kolada平台发布合并后的最终结果。
