Description

What-if analysis is a scenario modeling technique where you make a hypothetical change to a time series and compare the forecasts generated by these changes against the baseline, unchanged time series. It is important to remember that the purpose of a what-if analysis is to understand how a forecast can change given different modifications to the baseline time series. For example, imagine you are a clothing retailer who is considering an end of season sale to clear space for new styles. After creating a baseline forecast, you can use a what-if analysis to investigate how different sales tactics might affect your goals. You could create a scenario where everything is given a 25% markdown, and another where everything is given a fixed dollar markdown. You could create a scenario where the sale lasts for one week and another where the sale lasts for one month. With a what-if analysis, you can compare many different scenarios against each other. Note that a what-if analysis is meant to display what the forecasting model has learned and how it will behave in the scenarios that you are evaluating. Do not blindly use the results of the what-if analysis to make business decisions. For instance, forecasts might not be accurate for novel scenarios where there is no reference available to determine whether a forecast is good. The TimeSeriesSelector object defines the items that you want in the what-if analysis.

Parameters

-ClientConfig <AmazonForecastServiceConfig>
Amazon.PowerShell.Cmdlets.FRC.AmazonForecastServiceClientCmdlet.ClientConfig
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Force <SwitchParameter>
This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-ForecastArn <String>
The Amazon Resource Name (ARN) of the baseline forecast.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
-PassThru <SwitchParameter>
Changes the cmdlet behavior to return the value passed to the WhatIfAnalysisName parameter. The -PassThru parameter is deprecated, use -Select '^WhatIfAnalysisName' instead. This parameter will be removed in a future version.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-S3Config_KMSKeyArn <String>
The Amazon Resource Name (ARN) of an Key Management Service (KMS) key.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesTimeSeriesSelector_TimeSeriesIdentifiers_DataSource_S3Config_KMSKeyArn
-S3Config_Path <String>
The path to an Amazon Simple Storage Service (Amazon S3) bucket or file(s) in an Amazon S3 bucket.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesTimeSeriesSelector_TimeSeriesIdentifiers_DataSource_S3Config_Path
-S3Config_RoleArn <String>
The ARN of the Identity and Access Management (IAM) role that Amazon Forecast can assume to access the Amazon S3 bucket or files. If you provide a value for the KMSKeyArn key, the role must allow access to the key.Passing a role across Amazon Web Services accounts is not allowed. If you pass a role that isn't in your account, you get an InvalidInputException error.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesTimeSeriesSelector_TimeSeriesIdentifiers_DataSource_S3Config_RoleArn
-Schema_Attribute <SchemaAttribute[]>
An array of attributes specifying the name and type of each field in a dataset.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesTimeSeriesSelector_TimeSeriesIdentifiers_Schema_Attributes
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'WhatIfAnalysisArn'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.ForecastService.Model.CreateWhatIfAnalysisResponse). Specifying the name of a property of type Amazon.ForecastService.Model.CreateWhatIfAnalysisResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Tag <Tag[]>
A list of tags to apply to the what if forecast.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesTags
-TimeSeriesIdentifiers_Format <String>
The format of the data, either CSV or PARQUET.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesTimeSeriesSelector_TimeSeriesIdentifiers_Format
-WhatIfAnalysisName <String>
The name of the what-if analysis. Each name must be unique.
Required?True
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesAK
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-EndpointUrl <String>
The endpoint to make the call against.Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-ProfileLocation <String>
Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials.If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesAWSProfilesLocation, ProfilesLocation
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesStoredCredentials, AWSProfileName
-Region <Object>
The system name of an AWS region or an AWSRegion instance. This governs the endpoint that will be used when calling service operations. Note that the AWS resources referenced in a call are usually region-specific.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesRegionToCall
-SecretKey <String>
The AWS secret key for the user account. This can be a temporary secret key if the corresponding session token is supplied to the -SessionToken parameter.
Required?False

Outputs

System.String or Amazon.ForecastService.Model.CreateWhatIfAnalysisResponse
This cmdlet returns a System.String object. The service call response (type Amazon.ForecastService.Model.CreateWhatIfAnalysisResponse) can also be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.
