En el siguiente ejemplo, tengo un marco de datos que consiste en una serie temporal de mediciones de temperatura del agua registradas a 5 profundidades en el océano donde cada valor Tempcorresponde a la fecha DateTimey la profundidad Depth.
set.seed(1)
Temp <- rnorm(43800,sd=20)
AirT <- rnorm(8760,sd=20)
Depth <- c(1:5)
DateTime = seq(from=as.POSIXct("2010-01-01 00:00"),
to=as.POSIXct("2010-12-31 23:00"), length=8760)
Time <- as.POSIXct(DateTime, format = "%Y-%m-%d %H:%M")
DatT <- data.frame(Temp)
## bind together
FinalDat <- cbind(DatT, Date = rep(Time,5))
FinalDat <- cbind(FinalDat, AirT = rep(AirT, 5),
Depth = rep(Depth, each = 8760),
Doy = as.numeric(format(Time,format = "%j")),
DecTime = rep(seq(1,366, length = 8760),5))
A partir de esto, me gustaría encontrar la similitud entre la temperatura del aire ( AirT) y la temperatura del agua a estas diferentes profundidades. Puedo calcular la correlación entre la temperatura del aire y la temperatura del agua para las diferentes profundidades, lo que muestra que la correlación disminuye con la profundidad, sin embargo, estoy buscando un método más sofisticado (que no sea recibir un solo valor para cada serie de tiempo). ¿Alguien puede sugerir un método apropiado para lograr esto?
Aquí hay una versión reducida de mi data.frame (FinalDat):

. Un análisis de la relación interna de Y versus X arrojó un modelo típico de la forma
. Elegí agregar otro término AR al ruido para propósitos de una expresión más general. Los cuatro ejemplos están significativamente influenciados por las anomalías, por lo que se podría argumentar / sugerir que se debe continuar con series ajustadas de forma atípica o series eliminadas por intervención, es decir, "series limpias". Para fines de presentación aquí, esto no se hizo. Ahora procedimos a estimar el "modelo típico" para cada uno de los 4 conjuntos de datos Y para el compuesto. Esto rindió 
. La prueba F es simplemente la prueba de Chow para parámetros constantes
La "similitud" depende del problema. Por lo que escribe, tengo la sensación de que la estimación de los espectros cruzados y la coherencia podría ser una buena manera de proceder, al menos si sus series son estacionarias y lo suficientemente largas. Otras referencias que tengo a mano y que pueden o no ser relevantes para su problema son:

El espectro cruzado es solo la transformación de Fourier de la función de correlación cruzada. La correlación cruzada debe ser alta en el retraso 0 y puede disminuir a medida que aumenta la diferencia de tiempo entre las series. Esto debe hacerse si ambas series son estacionarias. Si hay tendencias o cambios estacionales en la temperatura, podría ajustar las tendencias temporales o las funciones del coseno a las dos series y buscar similitudes en los coeficientes del modelo. Para las series estacionarias, se podría hacer lo mismo para los modelos ARMA instalados. ¿Las series que mejor se ajustan tienen los mismos pedidos p y q? Si es así, ¿qué tan cerca están las estimaciones de los parámetros?
