returns the ratio of liquidation costs due to liquidity
demand by stock for an equal investment value, or liquidity factor.
`lf`

)`liquidityFactor`

uses the Kissell
Research Group (KRG) transaction cost analysis object
`k`

and trade data
`trade`

.

For details about the formula and calculations, contact the Kissell Research Group.

You can expand the LF model to include a stock-specific factor such as market capitalization, beta, P/E ratio, and Debt/Equity ratio. In this case, $${X}_{k}$$ denotes the stock-specific factor and $${a}_{k}$$ denotes the corresponding shape parameter. For details about implementing an expanded LF model, contact the Kissell Research Group.
