| -- The following snippet calculates the extended internal rate of return | |
| -- for an investment, provided the list of transactions made during the time. | |
| -- | |
| -- It expects a table `transactions` to be present (of-course feel free to rename) | |
| -- with two columns, date and amount, where date is the date of the transaction | |
| -- and amount being the amount of the transaction. Each outflow (like, money put into the investment) | |
| -- must be a negative value and each inflow (like, money take out from investment) must be positive. | |
| -- | |
| -- P.S. This snippet depends on POWER(...) function from [https://github.com/nalgeon/sqlean]. | |
| -- Either import that or provide your own. |
