Questions tagged [binary-data]

A binary variable takes one of two values, typically coded as "0" and "1".

In a broader sense "binary variable" is a synonym of "dichotomous variable": any variable that can take on only one of two values. In a narrower sense it refers to dichotomous data coded as "1" or "0". (Sometimes "1" is supposed to mean "is present" and "0" to mean "is absent", which may require handling the two values asymmetrically in some statistical analyses (see e.g. Jaccard indices).)

A binary response variable occurs as a result of Bernoulli trials, whose analysis commonly involves contingency tables or logistic/probit regression.

The term 'binary' also refers to data stored as machine-readable binary numbers rather than numbers recorded in strings of ASCII (or Unicode, or other human-readable) numerals.

In econometrics binary variables are also called dummy variables.

Models for binary response that appear like logit/probit regression but never approach 1

I'm reading the textbook "Introduction to Econometrics" by Stock and Watson. Chapter 11 discusses regression with a binary response and it teaches the logit/probit models mostly. These seem to make sense when the plots show an S shaped relationship…

Significance of binary variables

If I have variables $X_1$, $X_2$, ... $X_n$ whose values are only 1 or 0, in order to explain a variable $Y$, is there a way to determine which ones are significant, and also, how could it be measured?
