Returns

A reference to the missing count by columns.

pub const fn missing_count_by_rows(&self) -> &Array1<usize>

Get the count of missing values in each row.

Returns

A reference to the missing count by rows.

pub const fn missing_rate(&self) -> f64

Get the overall missing rate in the table.

Returns

The percentage of missing values.

pub const fn missing_rate_by_cols(&self) -> &Array1<f64>

Get the missing rate in each column.

Returns

A reference to the missing percentage by columns.

pub const fn missing_rate_by_rows(&self) -> &Array1<f64>

Get the missing rate in each row.

Returns

A reference to the missing percentage by rows.

pub const fn missing_correlation(&self) -> &Array2<f64>

Get the missing (Pearson) correlation matrix.

Returns

A reference to the missing correlation matrix.

pub const fn missing_covariance(&self) -> &Array2<f64>

Get the missing (unbiased) covariance matrix.

Returns

A reference to the missing covariance matrix.

pub const fn complete_cols_count(&self) -> usize

Get the count of complete columns (without any missing values) in the table.

Returns

The count of complete columns.

pub const fn complete_rows_count(&self) -> usize

Get the count of complete rows (without any missing values) in the table.

Returns

The count of complete rows.
