This function converts a transformation name to the corresponding function. Convertion is from original scale to real scale by default. Available transformations:
exp4
: $(4x)$, inverse is $(x)/4$
exp2
: $(2x)$, inverse is $(x)/2$
tanh
: Hyperbolic tangent transformation used for AR1 parameter, uses ar1_th2a and ar1_a2th
identity
: Identity function, no transformation
exp
: $(x)$, inverse is $(x)$
sqrt
: $(x)$, inverse is $x^2$
square
: $x^2$, inverse is $(x)$
log
: $(x)$, inverse is $(x)$
