Call data records

This is a pre-processed subset of the call data records dataset from the Data for Development: the D4D Challenge on Mobile Phone Data. The dataset consists of 8 time series of 3336 time steps sampled at hourly resolution. The 8 time series represent: The number of incoming calls in the area covered by the antenna. The volume in minutes of the incoming calls in the area covered by the antenna. The number of outgoing calls in the area covered by the antenna. The volume in minutes of the outgoing calls in the area covered by the antenna. The sine of the hour of the day when the telephone activity has been registered. The cosine of the hour of the day when the telephone activity has been registered. The sine of the day of the week when the telephone activity has been registered. The cosine of the day of the week when the telephone activity has been registered. This image shows the first 500 hours in each time series (time series 5-6 and 7-8 are plot together).

本数据集为「数据促进发展：D4D移动手机数据挑战赛（Data for Development: the D4D Challenge on Mobile Phone Data）」所提供的通话记录数据集的预处理子集。该数据集包含8组时间序列，每组均包含3336个时间步，采样频率为每小时1次。这8组时间序列分别对应以下内容：天线覆盖区域内的呼入通话次数；天线覆盖区域内呼入通话的总时长（单位：分钟）；天线覆盖区域内的呼出通话次数；天线覆盖区域内呼出通话的总时长（单位：分钟）；通话活动记录时刻的当日小时数的正弦值；通话活动记录时刻的当日小时数的余弦值；通话活动记录时刻的当周天数的正弦值；通话活动记录时刻的当周天数的余弦值。本配图展示了每组时间序列的前500小时数据（第5、6组及第7、8组时间序列合并绘图）。
