Scipy stats package
Two populations The IQ metrics are bimodal, as if there are 2 sub-populations. Plotting simple quantities of a pandas dataframe. Linear models, multiple factors, and analysis of variance 3. The data can than be seen as a 2D table, or matrix, with columns giving the different attributes of the data, and rows the observations. Given two set of observations, x and ywe want to test the hypothesis that y is a linear function of x.
An overview of statistical functions is given below. . For many more stat related functions install the software R and the interface package rpy.

In the code samples below we assume that the ttest_ind (a, b, axis=0, equal_var=True.
Calculates the T-test for the mean of ONE group of scores. DataFramefrom the pandas module. Given two set of observations, x and ywe want to test the hypothesis that y is a linear function of x. Exercise Plot the scatter matrix for males only, and for females only.
This module contains a large number of probability distributions as well as a growing library of statistical functions.
Data representation and interaction 3.

A normal continuous random variable. The location (loc) keyword.
Scipy is a vast library. We will store and manipulate this data in a pandas. Note For a quick view on a large dataframe, use its describe method: pandas. Given two set of observations, x and ywe want to test the hypothesis that y is a linear function of x. T-tests assume Gaussian errors.
R is a language dedicated to statistics.

To install Python and these dependencies, we recommend that you download Anaconda Python or Enthought Canopy, or preferably use the package manager .
DataFramefrom the pandas module. Hint : use tab-completion to find the relevent attribute.

We will store and manipulate this data in a pandas. Several of these functions have a similar version in the scipy. Python is a general-purpose language with statistics modules.

Multiple Regression. Full code for the figures 3.
It is different from a 2D numpy array as it has named columns, can contain a mixture of different data types by column, and has elaborate selection and pivotal mechanisms. You can test the same with a new array of the same length, but with a varied mean.
