1. A load estimation apparatus comprising a hardware processor configured to:
acquire sensor data from a measurement target;
calculate one or more posture loads relating to one or more body parts of the measurement target based on the sensor data;
perform, using information on the posture loads, first clustering of classifying the posture loads into a number of dimensions higher than the number of dimensions of the information on the posture loads to generate a first clustering result;
perform, using a distance from a representative sample in each cluster included in the first clustering result to each of a plurality of samples included in the information on the posture loads, second clustering of classifying the posture loads into a number of dimensions equal to or less than the number of dimensions of the first clustering to generate a second clustering result;
calculate a total load feature relating to the measurement target based on the second clustering result; and
and
display display data including a posture load graph in which the calculated one or more posture loads are illustrated in time series and a graph based on the calculated total load feature.
