inv_return_table()[source]

Table of investment return rates

Returns a Series of monthly investment retuns. The Series is indexed with scen_id and t which is inherited from std_norm_rand.

$\exp\left(\left(\mu-\frac{\sigma^{2}}{2}\right)\Delta{t}+\sigma\sqrt{\Delta{t}}\epsilon\right)-1$

where $$\mu=2\%$$, $$\sigma=3\%$$, $$\Delta{t}=\frac{1}{12}$$, and $$\epsilon$$ is a randome number from the standard normal distribution.
