1. A non-transitory computer-readable recording medium having stored therein a data clustering program that causes a computer to execute a process comprising:
calculating, for each of plural points included in a set of point group data, an eigenvector by using principal component analysis for a set of point group data that is present within a predetermined distance from a point;
calculating a curvature value of a multidimensional function having an extreme point that is a point positioned nearest to the eigenvector calculated, the curvature value representing a state of curving;
executing clustering of the plural points of the set of point group data by using a frequency distribution of curvature values for each of the plural points of the set of point group data as a feature value; and
outputting a result of execution of the clustering.
