Arguments
object 
an object returned by 
rSquaredLog 
logical.
If 
ela 
logical. If 
x 
an object returned by

Value
summary.cesEst
returns a list of class summary.cesEst
that contains the elements of the provided object
with with
following changes or additions:
coefficients 
a matrix with four columns: the estimated coefficients/parameters of the CES (including a possible fixed rho), their standard errors, the tstatistic, and corresponding (twosided) Pvalues. 
sigma 
square root of the estimated (asymptotic) variance of the random error (calculated without correcting for degrees of freedom). 
r.squared 
R^2value, i.e. the
â€˜fraction of variance explained by the modelâ€™.
If argument 
vcov 
covariance matrix of the estimated parameters (including a possible fixed rho). 
ela

the estimated elasticities of substitution,
their standard errors, the tstatistic,
and corresponding (twosided) Pvalues
(only if argument 
elaCov 
covariance matrix of the estimated
elasticities of substitution
