Functions ¶
func ConvertToPCAOutputData ¶
func ConvertToPCAOutputData(result *types.PCAResult, data *CSVData, includeMetrics bool, config types.PCAConfig, preprocessor *core.Preprocessor, categoricalData map[string][]string, targetData map[string][]float64) *types.PCAOutputData
ConvertToPCAOutputData converts PCAResult and CSVData to PCAOutputData
func GetDataSummary ¶
GetDataSummary returns a summary of the CSV data
func RunWithOSExit ¶
func RunWithOSExit()
RunWithOSExit runs the CLI and exits with appropriate code
func ValidateCSVData ¶
ValidateCSVData performs basic validation on parsed CSV data
Types ¶
type CSVData ¶
CSVData wraps the unified types.CSVData for backward compatibility
func ParseCSV ¶
func ParseCSV(filename string, options CSVParseOptions) (*CSVData, error)
ParseCSV reads and parses a CSV file according to the given options
