  1. What factors are most responsible for height?

  2. Model Specification Outcome = (Model) + Error ERROR??? measurement error model error analysis unexplained unknown unaccounted for missing variables

  3. Analytics & History: 1st Regression Line The first “Regression Line”

  4. Men's average height 'up 11cm since 1870s'

  5. Galton’s Notebook on Families & Height

  6. X4 X3 X5 Y X1 X2

  7. we find that a 54-loci genomic profile explained 4–6% of the sex- and age-adjusted height variance the Galtonian mid-parental prediction method explained 40% of the sex- and age-adjusted height variance

  9. Dataset Input Object Function Filename

  10. str() summary() Data Types: Numbers and Factors/Categorical

  11. head() summary() ece ece

  12. Outcome, Dependent Variable (Y-Axis) Outcome, Dependent Variable (Y-Axis) Smartphone? Yes or No Child’s Height Continuous Categorical Histogram Pie Bar Continuous Cross Table Scatter Frequency Predictor Variable (X-Axis) Parents Height Mosaic Cross Table Categorical Boxplot Gender 1 Logistic Regression Linear Regression Regression Model 0

  13. Frequency Distribution, Histogram hist(heights$childHeight)

  14. Standard Deviation Mean

  15. Calculating Standard Deviation - sd() • Deviation between mean and an actual data point.

  16. Normal Distribution and SD Mean = 66.5 S.D. = 3.6 66.5 - 7 = 59.4 66.5 + 7 = 73.6

  17. Density Plot plot(density(h$childHeight)) Area = 1

  18. Mode, Bimodal hist(h$childHeight,freq=F, breaks =25, ylim = c(0,0.14)) curve(dnorm(x, mean=mean(h$childHeight), sd=sd(h$childHeight)), col="red", add=T) Bimodal: two modes
