Distribution of Male and Female Heights

Joint Distribution of Sex and Sexual Orientation

A mosaicplot of the cross-classification of the 59946 users’ selected sex and sexual orientation:

Logistic Regression to Predict Sex

Linear regression (in red) and logistic regression (in blue) compared. Note both the x-axis (height) and y-axis (is female: 1 if user is female, 0 if user is male) have random jitter added to better visualize the number of points involved for each (height x sex) pair.

Fitted probabilities p-hat of each user being female along witha decision threshold (in red) used to predict if user is female or not.
