Display Mean of Crosstab-CodePudding

I have a dataframe 'df'. I want to display all rows of the 'Percentage of 1/Yes' column that are greater than the average of the column. My code displays whether it is True/False, but I want to display the actual value for the True rows and not display the False rows.

My code:

trainData, validData = train_test_split(df, test_size=0.4, random_state=1)

# Response rate for RFM categories
# RFM: Combine R, F, M categories into one category
trainData['RFM'] = trainData['Mcode'].astype(str)   trainData['Rcode'].astype(str)   trainData['Fcode'].astype(str)

rfm_crosstab = pd.crosstab(index = [trainData['RFM']], columns = trainData['Florence'], margins = True)
rfm_crosstab['Percentage of 1/Yes'] = 100 * (rfm_crosstab[1] / rfm_crosstab['All'])

# Display rows with percentage greater than mean
rfm_crosstab['Percentage of 1/Yes'] > rfm_crosstab['Percentage of 1/Yes'].mean()

Output:

121     True

CodePudding user response：

Almost there, you can use your output (True/False column) the following way:

output = rfm_crosstab['Percentage of 1/Yes'] > rfm_crosstab['Percentage of 1/Yes'].mean()
rfm_crosstab['Percentage of 1/Yes'][output]
