Correlation stability coefficient

Share:

Description

This coefficient denotes the estimated maximum number of cases that can be dropped from the data to retain, with 95% probability, a correlation of at least 0.7 (default) between statistics based on the original network and statistics computed with less cases. This coefficient should not be below 0.25 and is preferably above 0.5. See also Epskamp, Borsboom and Fried (2016) for more details.

Usage

1
corStability(x, cor = 0.7, statistics = c("strength", "closeness", "betweenness"))

Arguments

x

Output of bootnet. Must be case-drop bootstrap.

cor

The correlation level tot est at.

statistics

The statistic(s) to test for.
