pts: The total phosphorus concentration and river discharge data...
In carx: Censored Autoregressive Model with Exogenous Covariates
Description
This data set contains the monthly total phosphorus concentration (P) and river discharge
(Q) of
West Fork Cedar River at Finchford, Iowa, USA, from 10/1998 to 10/2013. The P
data were collected under the ambient water quality program conducted by the
Iowa Department of Natural Resources (Iowa DNR), courtesy of Dr. K. E. Schilling from Iowa Geological Survey,
University of Iowa. The Q data were obtained from the website of U.S.
Geological Survey. A gap from 09/2008 to 03/2009 in the data are due to
program suspension owing to lack
of funding. The data contains logP and logQ which are the
logarithm of the original P and Q respectively. The P data are left censored,
with -1 or 0 in ci indicating that the corresponding observation is left censored or
observed. The lower censoring limits are stored in lcl. season is the quarter to which a month belong.
