Data quality check of continuous variables
Takes in a data, and returns summary of continuous variables
a data.frame or data.table
It is of utmost importance to know the distribution of continuous variables in the
dqcontinuous produces an output which tells - continuous variable,
non-missing values, missing values, percentage missing, minumum, average, maximum,
standard deviation, variance, common percentiles from 1 to 99, and number of outliers
for each continuous variable.
The function tags all integer and numeric variables as continuous, and produces output for them; if you think there are some variables which are integer or numeric in the data but they don't represent a continuous variable, change their type to an appropriate class.
dqcontinuous uses the same criteria to identify outliers as the one used for
box plots. All values that are greater than 75th percentile value + 1.5 times the
inter quartile range or lesser than 25th percentile value - 1.5 times the inter
quartile range, are tagged as outliers.
This function works for both 'data.frame and 'data.table' but returns a 'data.frame' only.
a data.frame which contains the non-missing values, missing values, percentage of missing values, mimimum, mean, maximum, standard deviation, variance, percentiles and count of outliers of all integer and numeric variables
