The rating corresponds to the degree to which the auto is riskier than its price indicates.\n \nCars are initially assigned a risk factor symbol associated with its price. Then, if it is riskier (or less), this symbol is adjusted by moving it up (or down) the scale. Actuaries call this process \"symboling\". A value of +3 indicates that the auto is risky, -3 that it is probably pretty safe.\n\n\n# Content\nThe original data set is in the [UCI Machine Learning Repository](https://archive.ics.uci.edu/ml/datasets/Automobile).\n\nThis data set contains 205 instances (cars), each of them has 26 attributes: 15 continuous, 1 integer, and 10 nominal. Some attributes have missing values.\n\n\n# Training Data and Test Data\nThe training data is randomly chosen 144 (70%) instances and the test data is the remaining 61 (30%) instances.\n\n# Notice\nThis is limited competition in [MPRG](http://mprg.jp/) and [1056Lab](https://1056lab.org), a data mining laboratory at [Chubu University](https://www3.chubu.ac.jp/main/english/), Japan.\n\n# Reference\n-[Jeffrey C.
