LinearFactorModel: Linear Factor Model Base

LinearFactorModelR Documentation

Linear Factor Model Base

Description

Base class for multi-factor OLS models used in event studies. All factor models (Market Model, Fama-French, Carhart) share the same estimation approach: OLS regression of excess returns on factor returns during the estimation window.

Super class

ModelBase -> LinearFactorModel

Public fields

model_name

Name of the model.

formula

The regression formula.

required_columns

Columns required in the data.

use_hac

Logical. Use HAC (Newey-West) standard errors.

hac_lag

Integer or NULL. Lag truncation for Newey-West.

Methods

Public methods


LinearFactorModel$new()

Create a new LinearFactorModel.

Usage
LinearFactorModel$new(use_hac = FALSE, hac_lag = NULL)
Arguments
use_hac

Logical. Use HAC (Newey-West) standard errors.

hac_lag

Integer or NULL. Lag truncation for Newey-West.


LinearFactorModel$fit()

Fit the linear factor model via OLS on the estimation window.

Usage
LinearFactorModel$fit(data_tbl)
Arguments
data_tbl

Data frame or tibble containing the data to fit.


LinearFactorModel$abnormal_returns()

Calculate abnormal returns as observed minus predicted.

Usage
LinearFactorModel$abnormal_returns(data_tbl)
Arguments
data_tbl

Data frame or tibble.


LinearFactorModel$clone()

The objects of this class are cloneable with this method.

Usage
LinearFactorModel$clone(deep = FALSE)
Arguments
deep

Whether to make a deep clone.
