# RemoveOutlierByIndex

Advanced Analysis Library Only

AnalysisLibErrType RemoveOutlierByIndex (double arrayX[], double arrayY[], double weight[], int *numberOfElements, int indices[], int numberOfIndices);

## Purpose

Removes the outliers specified by indices.

## Parameters

Input
Name | Type | Description
indices | integer array | The indices of the outliers.
numberOfIndices | integer | The length of indices.
Output
Name | Type | Description
arrayX | double-precision array | On input, arrayX is the array of x values. On output, arrayX is the array of x values with the outliers removed.
arrayY | double-precision array | On input, arrayY is the array of y values. On output, arrayY is the array of y values with the outliers removed.
weight | double-precision array | On input, weight is the array of weights. On output, weight is the array of weights with the outliers removed. If weight is NULL, the function does not change weight.
numberOfElements | integer | On input, numberOfElements specifies the number of observations in arrayX, arrayY, and weight. On output, numberOfElements specifies the number of remaining observations in arrayX, arrayY, and weight after the outlier observations are removed.

## Return Value

Name | Type | Description
status | AnalysisLibErrType | A value that specifies the type of error that occurred. Refer to analysis.h for definitions of these constants.
