Title: | Data Sets for Copula Modeling |
---|---|
Description: | Data sets used for copula modeling in addition to those in the R package 'copula'. These include a random subsample from the US National Education Longitudinal Study (NELS) of 1988 and nursing home data from Wisconsin. |

Random sample of size 1000 from the US National Education Longitudinal Study (NELS) data containing the mathematics, science and reading scores, together with covariates, of 8th graders in 1988.
data("NELS88")
data("NELS88")
data.frame
containing the identification
number of the school to which the student belongs (ID
),
the standardized score of the student on a
mathematics achievement test (Math
; rescaled by an Item
Response Theory (IRT) method where a higher score indicates greater
proficiency in mathematics), the standardized
score of the student on a science achievement test (Science
),
the standardized score of the student on a reading achievement test
(Reading
), a factor indicating whether the student is a member
of an ethnic minority group (Minority
), a numeric measure of
the socio-economic status of the student and family (SES
), a
factor indicating whether the student is female (Female
), a
factor indicating whether the school is publicly funded
(Public
), the size of the student's school (Size
),
a factor indicating whether the school is located in an urban environment
(Urban
) and a factor indicating whether the school is located in a
rural environment (Rural
).

Data set containing the occupancy rate (utilization) and covariates of 377 nursing homes in Wisconsin between 1995 and 2001.
data("nursingHomes")
data("nursingHomes")
data.frame
containing the nursing home identification
number (ID
), the occupancy rate (Rate
; see Sun et
al. (2008, Equation (7)) for how this is computed), the logarithmic
number of beds of the nursing home (LnNumBed
), the logarithmic
net square foot of the nursing home (LnSqrFoot
), the cost
report year (CRYear
), indicators whether the nursing home runs
on a for-profit basis (Pro
), whether it is tax exempt
(TaxExempt
), whether it has self funding of insurance
(SelfIns
), whether it is accredited as Medicare Certified
(MCert
) and whether it is located in an urban environment
(Urban
); see Sun et al. (2008, Table 2).
