    • The risk measures of a portfolio are calculated with speed. Concerning a loss for each of the sectors to which the companies constituting the portfolio belong, the Laplace transform of a conditional probability distribution in which factors affecting management indexes are respective values is calculated in advance and stored in a storage unit as data. The stored data is retrieved as an approximate value and used when a numerical calculation of an integral is performed, to perform the integration. Consequently, as it becomes possible to quickly calculate the Laplace transform of a density function and a distribution function, it is possible to calculate the density function and the distribution function by Laplace inversion and calculate the risk measures of the portfolio.
    • 投资组合的风险度量以速度计算。 关于构成投资组合的公司的每个部门的损失,预先计算影响管理指标的因素是相应值的条件概率分布的拉普拉斯变换,并作为数据存储在存储单元中。 存储的数据被检索为近似值,并且当执行积分的数值计算时使用,以执行积分。 因此,由于可以快速计算密度函数和分布函数的拉普拉斯变换,因此可以通过拉普拉斯反演计算密度函数和分布函数,并计算投资组合的风险度量。

    • A touch sensor function-equipped display device includes: a first substrate that has a common electrode; a second substrate that is disposed to face the first substrate; a display unit that is disposed between the first substrate and the second substrate; and a touch sensor that detects a touch position on a touch surface disposed on the first substrate side or the second substrate side. The second substrate includes: a plurality of data lines that are aligned in a row direction; and a plurality of capacitance lines that are aligned in a column direction approximately perpendicular to the data lines. The touch sensor includes an electric-potential rise rate detecting unit that detects a magnitude of parasitic capacitance generated near each intersection of the plurality of capacitance lines and the plurality of data lines as the rise rate of an electric potential of the data line at the time of application of a voltage to the capacitance line defining the each intersection and detects a position near the intersection in which the rise rate of the electric potential detected by the electric-potential rise rate detecting unit is out of a predetermined range as the touch position.
