snowflake.snowpark.DataFrameStatFunctions¶
- class snowflake.snowpark.DataFrameStatFunctions(dataframe: DataFrame)[source]¶
- Bases: - object- Provides computed statistical functions for DataFrames. To access an object of this class, use - DataFrame.stat.- Methods - approxQuantile(col, percentile, *[, ...])- For a specified numeric column and a list of desired quantiles, returns an approximate value for the column at each of the desired quantiles. - approx_quantile(col, percentile, *[, ...])- For a specified numeric column and a list of desired quantiles, returns an approximate value for the column at each of the desired quantiles. - corr(col1, col2, *[, statement_params])- Calculates the correlation coefficient for non-null pairs in two numeric columns. - cov(col1, col2, *[, statement_params])- Calculates the sample covariance for non-null pairs in two numeric columns. - crosstab(col1, col2, *[, statement_params])- Computes a pair-wise frequency table (a - contingency table) for the specified columns.- sampleBy(col, fractions[, seed])- Returns a DataFrame containing a stratified sample without replacement, based on a - dictthat specifies the fraction for each stratum.- sample_by(col, fractions[, seed])- Returns a DataFrame containing a stratified sample without replacement, based on a - dictthat specifies the fraction for each stratum.
