Logistic regression problem: propensity score matching
...e is as follows: londonpsm <- sqlFetch(channel, "London_NW_london_pilots_elig", rownames=ORCID) attach(londonpsm) mod.multinom <- multinom(sample ~ AGE + DISABLED + GENDER + ETHCODE + NDYPTOT + NDLTUTOT + LOPTYPE) lonoutput <- predict(mod.multinom, sample, type='probs') london2 <- data.frame(lonoutput) The Logistic regression seems to work, although summary() says the it is not a matrix. The output looks like odds ratios, but I would like to know whether this is so. Thank you Paul Bivand
