1. A method of identifying software texts likely to include faults, the method comprising: calculating, by a computing device, values of numerical coefficients included in a first set of equations representing linear combinations, the first set of equations including values of feature vectors associated with a first set of software texts, the first set of equations including values of fault counts associated with the first set of software texts; calculating, by the computing device, values of fault counts using a second set of equations representing linear combinations, the calculated values of fault counts being associated with a second set of texts, the second set of equations including the calculated values of the numerical coefficients included in the first set of equations and values of feature vectors associated with the second set of texts; and ranking, by the computing device, the second set of software texts based on the values of fault counts associated with the second set of equations.
