A non-transitory computer-readable recording medium stores therein a learning program that causes a computer to execute a process including calculating, by secure computation, an objective variable by inputting an explanatory variable into a logistic regression model, updating parameters of the logistic regression model by secure computation based on a result of calculation, and determining, by secure computation, whether to end update of the parameters based on whether an update amount of the parameters is smaller than a reference value that has been specified by a user and is encrypted.
