Functions to determine the presence/absence of certain model parameter types using their names. Intended largely for convenience and internal use.
isInt(x)isInx(x)
isPhi(x)
isR2(x)
isRaw(x)
A logical vector of the same length as x.
A character vector of parameter names (e.g. names of coefficients
from coef() or stdEff()).
isInt(): Is parameter an intercept?
isInx(): Is parameter a variable interaction (product term)?
isPhi(): Is parameter a beta regression precision coefficient?
isR2(): Is parameter an R-squared value?
isRaw(): Is parameter a raw (unstandardised) coefficient?
