Computes empirical transition counts, estimates transition probabilities by
maximum likelihood, and performs likelihood-ratio tests against the
actor-only
and partner-only constrained models to identify the univariate pattern of
interaction.
Usage
univariatePattern(chainFM, chainSM, states, alpha = 0.05)
Arguments
- chainFM
Vector of observed states for the first member (FM).
- chainSM
Vector of observed states for the second member (SM).
- states
A single integer >= 2 giving the number of states.
- alpha
A single number in (0, 1) giving the significance level.
Default is 0.05.
Value
A list with class c("dyadic_pattern", "list") containing two
htest objects (TEST.AM, TEST.PM), a string
pattern, and metadata fields alpha, states, and
call. It remains usable as an ordinary list.
Details
Pattern labels summarize which structure is retained by the tests:
IM (A0) denotes an independence pattern, APM (A1) an
actor-partner pattern, AM (A2) an actor-only pattern, and
PM (A3) a partner-only pattern.
Examples
chainFM <- c(1L, 2L, 1L, 2L, 2L, 1L)
chainSM <- c(2L, 1L, 2L, 1L, 1L, 2L)
univariatePattern(chainFM, chainSM, states = 2L, alpha = 0.05)
#> Dyadic interaction pattern
#> Pattern: IM (A0)
#> Alpha: 0.05
#> States: 2
