kandi X-RAY | isoweek Summary

isoweek is a Go library typically used in Utilities, Date Time Utils applications. isoweek has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

[Go Report Card] The Go package isoweek calculates a starting date and time of ISO 8601 week. ISO 8601 standard defines the common week numbering system used in Europe and many other countries. Monday is the first day of a week. The Go standard library "time" package has ISOWeek() function for getting ISO 8601 week number of a given Time, but there is no reverse functionality for getting a date from a week number. This package implements that. Invalid input is silently accepted. There is a separate Validate() function if week number validation is needed. There are also functions for working with Julian day numbers. Using Julian day numbers is often the easiest and fastest way to do date calculations. This package does not work with the week system used in US/Canada/Australia (weeks starting on Sundays). However the Julian day number functions may be still useful.

How to populate 2 columns in DataFrame with same "def" function?

Asked 2022-Apr-03 at 18:51

I have a data frame that has a date column, what I need is to create another 2 columns with the "start of week date" and "end of week date". The reason for this is that I will then need to group by an "isoweek" column... but also keep this two-column "start_of_week_date" and "end_of_week_date"

I've created the below function:

Hope I understand correctly, Refer this dt.weekday for caculating week start & week end, here I've used 6 for 'Sunday' if you need any other day as weekend then give the appropriate number.

The day of the week with Monday=0, Sunday=6

How to filter the a column with isoweek values in BigQuery in StandardSQL?

Asked 2021-Dec-17 at 06:55

I have the following table where I want to filter only the last 4 weeks - challenge: the date range of the underlying table must be from 2018 - 2021 so that all other columns can be filled. Filtering the date did not work for me, because then I wouldn't get data for the columns of the previous year.

How can I filter the table so that I always get the last 4 weeks from today but also have the data of all other columns?

Date format error while forecasting using tsibble objects

Asked 2021-Dec-07 at 13:28

I have converted a normal DF into a tsibble object and used that for my time-series forecasting. While fitting the model I experience the date format error- "Error in decimal_date.default(x) : date(s) not in POSIXt or Date format". As you could see from the below code- the converted tsibble object clearly identifies column "Week.1" as week date type. Could you please help me clarify why I'm still getting the date format when I fit forecast models to the tsibble object?

ANSWER

Answered 2021-Dec-07 at 13:28

You are mixing 2 different ways of doing forecasts. you either use fable or you use forecast. auto.arima is from the forecast package. Though it does work with fable, it is better to keep everything to the same package eco system. Fable is the successor of forecast. Your library loading problably conflicted somewhere.

For arima forecasts check out chapter 9.7 from Forecasting: Principles and Practice 3rd edition.

I adjusted your code to work with fable. I have included 2 ways of doing this. My preference is the second one, because then you can see the difference in AICc values and see that they are very close to each other.
