kandi X-RAY | quant Summary

quant is a Ruby library typically used in Server, Application Framework, Ruby On Rails applications. quant has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

An open source Rails API to track "quantified self" data. Right now, the hardware companies in this space are storing your data in closed systems. Let's change that. Take the Withings WiFi scale or the FitBit, for example. Both are essential pieces of the quantified self hacker, yet both store your data in their respective, siloed databases. What happens when one of them goes bust? Or decides to pivot towards an ad-based business model?. This project includes a Rails + Postgres RESTful API to store your data.

Problem minimising a function using L-BFGS-B method in R?

Asked 2022-Jan-08 at 02:02

A similar question was asked here but it didn't receive any answers.

I have a function that I need to minimize. My function has 3 parameters, x, y, and w. Given w, I need to find the optimal pair of x and y that minimizes my function. However, x and y are restricted in the interval (-0.5 ,0.5]

I tried to use the optim function and it works when I don't have restrictions. However, when I apply the restrictions and use the L-BFGS-B method, I get an error. I cant figure out why I am getting this error.

Below is an example of my function and some of the methods I have tried. This is the function that Im trying to minimize:

ANSWER

First

11 and 12 means: Not item, the item column is 1 and 2 meaning that your grouping variable ggroup has 2 items or two levels.

11 and 12 are row names: if you wrap the whole thing around tibble() thy will disappear. In detail they mean first 1 = variable1, second 1 of 11 means level or item 1 of the grouping variable. You can get it if you follow the example at the end.

Second

You can analyze the complete dataset grouped with this formula input: describeBy(data_excel ~ ggroup)

Error applying facet_wrap() in geom_sf() incomplete polygon in ggplot R

Asked 2021-Nov-07 at 17:43

I have a shapefile with 7 regions. I have an excel file with data about reptiles in these 7 regions. I merged this shapefile with excel.

Using ggplot I tried to generate facet_wrap() from nome_popular, however the rest of the polygon parts were omitted in each facet created.

My tentative code

ANSWER

Answered 2021-Oct-31 at 05:58

The issue is that with faceting the data is splitted in groups and only the polygons contained in the splitted data will show up.

If you want all regions to be shown in each facet then one option would be to add a base map via second geom_sf layer. In your case + geom_sf(regiao) + geom_sf() should do the job.

As an example I make use of the default example from ?geom_sf:

QUESTION

How do I use lapply or sapply for boostraping or KM calculations on three different DFs when functions are nested?

Asked 2021-Oct-31 at 06:12

I want to run a bootstrap (k=10,000) and Kaplan-Meier calculations on the numeric column of three different data frames using lapply or sapply when functions are nested.

I have defined three functions to use as arguments in the command for boostrapping. One function returns a set of predefined quantiles, another the median, and a thrid a 95% confidence interval for the median. Bootstrapping fails altogether. The error I get for bootstrapping reads, "Error in x[, "Result", drop = FALSE] : incorrect number of dimensions"

KM only completes for the first data frame on the list (df).

I am using the boot and NADA2 libraries for the calculations.
