I have a matrix like this 0.05 0.13 1.2 0 0 0 0 0 red 0 0 0 0 0 0 0 0 white 0 0.06 0 0 0 0 0 0 blue If only 1 number in the first 8 columns is more than 0, in a new variable I write 1, if they're all 0 or less, I write 0, so 0.05 0.13 1.2 0 0 0 0 0 red 1 0 0 0 0 0 0 0 0 white 0 0 0.06 0 0 0 0 0 0 blue 1 I want to understand if the value of the new variable (1 or 0) is correlated to the colour.. I can use chi-square and what else? Anova and qhat else? And to correlated the first 8 columns to the colour, can I use logit? -- View this message in context: http://r.789695.n4.nabble.com/Which-function-for-this-tp3873856p3873856.html Sent from the R help mailing list archive at Nabble.com.
