sur {SIN} | R Documentation |
The data are simulated from a bivariate seemingly unrelated regressions model with two response variables (Y_1, Y_2) and two covariates (X_1, X_2). The sample is only of size 8.
data(sur)
A list providing a summary of the data. The list contains:
sur$means | : | the mean vector, |
sur$stddev | : | the vector of standard deviations, |
sur$corr | : | the correlation matrix, and |
sur$n | : | the sample size. |
The data were used by Drton \& Richardson (2004) to illustrate the possibility of a multimodal likelihood in seemingly unrelated regressions.
