Generate estimated monadic covariate effects for estimated mmsbm model
Description
The function estimates the effect of a shift in monadic covariate values on the probability of edge formation in the network.
Usage
covFX(fm, cov, shift, max.val = FALSE)
Arguments
fm |
An object of class |
cov |
Character string identifying the monadic covariate to be shifted. |
shift |
Numeric value specifying the desired increase or decrease in the monadic covariate. The monadic predictor will be shifted by this value for all nodes and time periods. |
max.val |
An optional numeric value specifying the maximum possible value for the monadic covariate. |
Value
List with named components:
- Overall Avg. Effect
Overall average effect of the covariate shift on the predicted probability of edge formation.
- Avg. Effect by Time
Vector of average effects of the covariate shift on the predicted probability of edge formation for each time period.
- Avg. Effect by Node
Vector of average effects of the covariate shift on the predicted probability of edge formation for each node.
- Avg. Effect by Dyad
Vector of average effects of the covariate shift on the predicted probability of edge formation for each node dyad.
- Avg. Effect Dyad-Time
Vector of estimated effects of the covariate shift on the predicted probability of edge formation for each node dyad-time unit.
