With hierarchical clustering, outliers often show up as one-point clusters.
Generate three Gaussian distributions to illustrate the effect of outliers.
set.seed(656)
x = c(rnorm(150, 0, 1), rnorm(150,9,1), rnorm(150,4.5,1))
y = c(rnorm(150, 0, 1), rnorm(150,0,1), rnorm(150,5,1))

Let
df = pd.DataFrame({'col_1':['A','B','A','B','C'], 'col_2':[3,4,3,5,6]})
df
# Output:
# col_1 col_2
# 0 A 3
# 1 B 4
# 2 A 3
# 3 B 5
# 4 C 6
To get the distinct values in col_1 you can use Series.unique()
df['col_1'].unique()
# Output:

If you have a dataframe with missing data (NaN, pd.NaT, None) you can filter out incomplete rows
df = pd.DataFrame([[0,1,2,3],
[None,5,None,pd.NaT],
[8,None,10,None],
[11,12,13,pd.NaT]],columns=list('ABCD'))

Probably the easies way to set up ruby on windows is to go to http://rubyinstaller.org/ and from there donwload an executable that you will install.
You don't have to set almost anything, but there will be one important window. It will have a check box saying Add ruby executable to your PATH. Confi...
Consider the ranges A1:A3 and B1:B3 having the same size and only number values, as below
=SUMPRODUCT(A1:A3,B1:B3)
This will loop through the ranges, taking the product of values in the same row and summing them, returning 32 in this example.
A1*B1 = 4
A2*B2 = 10
A3*B3 = 18
Consider the following ranges A1:A3 and B1:B3 as below
=SUMPRODUCT(--(A1:A3="c"),B1:B3)
This will first manipulate (A1:A3="c") into the following array
A1="c" = FALSE
A2="c" = FALSE
A3="c" = TRUE
Then apply the -- operator which converts...
Sometimes you need to make a script for someone but you are not sure what he has on his machine. Is there everything that your script needs? Not to worry. Bundler has a great function called in line.

Add the autodoc module in the extensions list present in the conf.py file at the root of your documentation:
extensions = [
'sphinx.ext.autodoc',
...
]
Autodoc needs to imports your modules to work.
You can include your code path in your conf.py file.
For instance:
import os
sys.path.insert(0, os.path.abspath('../src'))
Once a model is built predict is the main function to test with new data. Our example will use the mtcars built-in dataset to regress miles per gallon against displacement:
my_mdl <- lm(mpg ~ disp, data=mtcars)

Call:
lm(formula = mpg ~ disp, data = mtcars)
Coefficients:
