srm_arbsrm {srm}

Least Squares Estimation of the Social Relations Model (Bond & Malloy, 2018)

Description

Provides least squares estimation of the bivariate social relations model with missing completely at random data (Bond & Malloy, 2018a). The code is basically taken from Bond and Malloy (2018b) and rewritten for reasons of computation time reduction.

Usage

srm_arbsrm(data, serror = TRUE, use_srm = TRUE)

## S3 method for class 'srm_arbsrm'
coef(object, ...)
## S3 method for class 'srm_arbsrm'
summary(object, digits=3, file=NULL, ...)

Arguments

data

Rectangular dataset currently containing only one round robin group. Bivariate observations are stacked one below the other (see example dataset data.bm1).

serror

Logical indicating whether standard errors should be calculated.

use_srm

Logical indicating whether the rewritten code (TRUE) or the original code of Bond and Malloy (2018b) should be used.

object

Object of class srm_arbsrm

file

Optional file name for summary output

digits

Number of digits after decimal in summary output

...

Further arguments to be passed

Value

List containing entries

par_summary

Parameter summary table

est

Estimated parameters (as in Bond & Malloy, 2018b)

se

Estimated standard errors (as in Bond & Malloy, 2018b)

Note

If you use this function, please also cite Bond and Malloy (2018a).
