1830 Hansen. Commentatio de gradus pr^ecisionis computatione. 

 [Goth a, 4to.] 



This was first printed " in einem Program, womit die hiesige 

 Sternwarte [at Gotha] des Jubilaum des wiirdigen Olbers gefeiert 

 hat." It contained a method for finding the weights of values deter- 

 mined by the Method of Least Squares, which for a small number of 

 unknown quantities is perha])S shorter than that of Gauss (1823).
