Dear R-users,
I need some assistance.
I am running some interactive variables for categorical variables.
I have dgen(2 levels converted to dummy variables)Â and dtoe(4-levels also
converted to dummy variables). So I have worked with them in two ways:
i created a variable X1 = dgen*dtoe and I get an error "Error in dgen * dtoe
: non-conformable arrays"then i run a glm, binomial using that interaction
variable and i get : Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â logit_x =
glm(samp2$STATUS ~ dgen*dtoe, data=samp2,family = binomial("logit"))
> summary(logit_x)
Call:
glm(formula = samp2$STATUS ~ dgen * dtoe, family = binomial("logit"),
   data = samp2)
Deviance Residuals:
   Min      1Q  Median      3Q     MaxÂ
-2.6594Â Â 0.2431Â Â 0.2563Â Â 0.2563Â Â 0.2563Â
Coefficients: (5 not defined because of singularities)

(Dispersion parameter for binomial family taken to be 1)
   Null deviance: 269.48 on 999 degrees of freedom
Residual deviance: 266.56Â on 993Â degrees of freedom
AIC: 280.56
Number of Fisher Scoring iterations: 17
The thing is I need the coefficients, the p-values and t-values of all the
variables. In other words i do not want an output of NAs. How can I achieve
this?
Thanks alot.
