Force of mortality formula
The force of mortality μ ( x) uniquely defines a probability density function fX ( x ). The force of mortality can be interpreted as the conditional density of failure at age x, while f ( x) is the unconditional density of failure at age x. [1] The unconditional density of failure at age x is the product of the probability of … See more In actuarial science, force of mortality represents the instantaneous rate of mortality at a certain age measured on an annualized basis. It is identical in concept to failure rate, also called hazard function, in See more • The simplest example is when the force of mortality is constant: $${\displaystyle \mu (y)=\lambda ,}$$ then the survival function is $${\displaystyle S_{x}(t)=e^{-\int _{x}^{x+t}\lambda dy}=e^{-\lambda t},}$$ is the exponential … See more In a life table, we consider the probability of a person dying from age x to x + 1, called qx. In the continuous case, we could also consider the conditional probability of a person who has attained age (x) dying between ages x and x + Δx, which is See more • Failure rate • Hazard function • Actuarial present value • Actuarial science • Reliability theory See more WebForce of mortality. In actuarial science, force of mortality represents the instantaneous rate of mortality at a certain age measured on an annualized basis. It is identical in …
