Note that {it:exp} must not contain any additive constants nor equal signs (see {help lincom}). {title:Description} {p 4 4 2} {cmd:milincom} computes overall point estimates, standard errors, {it:t} statistics, {it:p}-values, and confidence intervals for linear combinations of regression coefficients after {help mifit}, using Rubin's combining rule. Results can optionally be displayed where appropriate as odds ratios, incidence rate ratios, or in generic "eform". {title:Options} {p 4 8 2} {cmdab:l:evel(}{it:#}{cmd:)} specifies the confidence level, in percent, for confidence intervals. {p 4 8 2} {cmd:or}, {cmd:irr}, and {cmd:eform} all do the same thing; they all report coefficient estimates as exp(b) rather than b. Standard errors and confidence intervals are similarly transformed. {cmd:or} is the default after {help logistic}. The only difference is how the output is labeled.
