# Class "regressionMulti"

### Description

Class "regressionMulti" holds the results of an original portfolio, its benchmark, and the results of regression analysis of a multi-period portfolio.

:Object of class

`"matrix"`

storing the active return of the input portfolio for each time period.`act.expo`

:Object of class

`"matrix"`

### Methods

- exposure
`signature(object = "regressionMulti")`

: Calculate and display the exposure of the input category of a portfolio.- plot
`signature(x = "regressionMulti", y = "missing")`

: Plot the exposure or the return of a regressionMulti class object.- returns
`signature(object = "regressionMulti")`

: Calculate the contribution of various effects based on the regression analysis.- show
`signature(object = "regressionMulti")`

: Summarize the essential information about the portfolio.- summary
`signature(object = "regressionMulti")`

: Summarize the portfolio and the regression-based attribution.
