Chapter 3. Statistical Data Analysis and Probability
We will cover the following recipes in this chapter:
- Fitting data to the exponential distribution
 - Fitting aggregated data to the gamma distribution
 - Fitting aggregated counts to the Poisson distribution
 - Determining bias
 - Estimating kernel density
 - Determining confidence intervals for mean, variance, and standard deviation
 - Sampling with probability weights
 - Exploring extreme values
 - Correlating variables with the Pearson's correlation
 - Correlating variables with the Spearman rank correlation
 - Correlating a binary and a continuous variable with the point-biserial correlation
 - Evaluating relationships between variables with ANOVA
 
Introduction
Various statistical distributions have been invented, which are the equivalent of the wheel for data analysts. Just as whatever I think of comes out differently in print, data in our world doesn't follow strict mathematical laws. Nevertheless, after visualizing our data, we can see that the data follows...
