Description Usage Arguments Details Value Examples
This function fits a model for individual-level moderator on hearsay accuracy. It requires a dataframe and either a model from the relevant model builder function or names of columns for self-reports, p2_reports, and id_mod_variable. The estimated parameters are:
1 2 3 | rep_accuracy_id_mods(data, model = NULL, target_self, p2_reports,
id_mod_variable, interaction_term, n_triads = length(target_self),
n_ts_per_p2s = 1, n_p2s_per_ts = 1)
|
data |
The dataframe that contains the ratings, moderator variable, and the interaction term. Data should be wide, with a row for every group of participants. At a minimum, it must contain four columns: one for target self-reports, one for mean-centered P2 reports, one for the mean-centered moderator variable, and one for the interaction term. |
model |
Optional. A model from the corresponding ReputationModelR model builder function. If this is supplied, no additional arguments need to be specified. |
target_self |
Quoted column names that contain target self-reports. If more than one is supplied, the order must match the other rating types. |
p2_reports |
Quoted column names that contain P2 reports, or ratings made by the person that knows the target indirectly through the corresponding P1. Ratings should be grand-mean-centered to increase the interpretibility of the model parameters. If more than one is supplied, the target-wise order must match the other rating types. |
id_mod_variable |
Quoted column names that contain the individual-level moderator of interest. If more than one is supplied from multiple exchangeable triads, the order must match the order of the ratings. Like P2-reports, the variable should be mean-centered to facilitate interpretability. |
interaction_term |
Quoted column names that contain the interaction term, or the product of the mean-centered P2-report and the mean-centered moderator variable. If more than one is supplied from multiple exchangeable triads, the target-wise order must match the order of the ratings. |
n_triads |
The number of exchangeable triads in each group. By default, this is determined by counting the number of target self-reports. This parameter rarely needs to be changed. |
n_ts_per_p2s |
The number of targets that each P2 rated. This defaults to 1. Currently, only values of 1 are supported. |
n_p2s_per_ts |
The number of P2s that rated each target;. This defaults to 1. Currently, only values of 1 are supported. |
The parameters for the individual-level moderator analyses are:
hearsay accuracy main effect; this should correspond to hearsay accuracy at average level of moderator variable (if data were properly mean-centered).
The meain effect of the moderator variable; it can be interpreted as the difference in target self-reports related to differences in the individual-level moderator variable.
This is the interaction term. It indicates the extent to which hearsay accuracy, depends on the moderator variable
