interaction

问题 I want to add the fitted function from GLM on a ggplot . By default, it automatically create the plot with interaction. I am wondering, if I can plot the fitted function from the model without interaction. For example, dta <- read.csv("http://www.ats.ucla.edu/stat/data/poisson_sim.csv") dta <- within(dta, { prog <- factor(prog, levels=1:3, labels=c("General", "Academic", "Vocational")) id <- factor(id) }) plt <- ggplot(dta, aes(math, num_awards, col = prog)) + geom_point(size = 2) + geom

问题 I am currently working in unity to make a few games. I am using C#. I am usually happy with the code in my game and i know how to make it 'elegant', so to speak. I am very good at coding individual elements (Say, the spaceship in Asteroids). But I am only happy with my code until I get to the point where one object needs to interact with another. It becomes a spaghetti of code after that point and i ALWAYS drop the project.. I have yet to find a graceful way of handling things. I believe I

问题 My Projects contains 6 qml Files: The main.qml opens a new ApplicationWindow and declares the toolbar. It also initalizes StackView with the initalItem homescreen.qml. On the Home Screen I have different buttons which open different qml Files, via stack.push("URL"). Besides the main.qml all Files start with Item{}. I've been able to connect signals from the main.qml and the home.qml. But I've been unable to access Objects that are deeper in the stack. I don't know if I hvae to change my .cpp

问题 I want to plot the regression surface from a model with an interaction term using rgl 's interactive plotting system. It is easy to plot a regression plane for a model without an interaction term using: plot3d(x=x1, y=x2, z=y1, type="s", col="yellow", size=1) planes3d(a=coef(mod1)[2], b=coef(mod1)[3], c=-1, d=coef(mod1)[1], alpha=.5) However, when the plane twists, this seems to be more difficult. Following on this question: 3D equivalent of the curve function in r, I am trying: f2 <-

问题 This question was migrated from Cross Validated because it can be answered on Stack Overflow. Migrated 4 years ago . Background The reference manual for the gbm package states the interact.gbm function computes Friedman's H-statistic to assess the strength of variable interactions. the H-statistic is on the scale of [0-1]. The reference manual for the dismo package does not reference any literature for how the gbm.interactions function detects and models interactions. Instead it gives a list

问题 I'm trying to create a .NET wrapper for media-file conversion using ffmepg, here is what I've tried: static void Main(string[] args) { if (File.Exists("sample.mp3")) File.Delete("sample.mp3"); string result; using (Process p = new Process()) { p.StartInfo.FileName = "ffmpeg"; p.StartInfo.Arguments = "-i sample.wma sample.mp3"; p.StartInfo.UseShellExecute = false; p.StartInfo.RedirectStandardOutput = true; p.Start(); //result is assigned with an empty string! result = p.StandardOutput

问题 xgb.fi() is a new function that works with xgboost to detect interactions between variables. The documentation can be found here: https://rdrr.io/github/RSimran/RXGBfi/man/xgb.fi.html This is an important subject and I tried to test the function but I run into an exception. See below for a reproducible example: library(data.table) library(xgboost) library(RXGBfi) data(mtcars) X = as.matrix(mtcars[, -9]) Y = mtcars$am dtrain = xgb.DMatrix(data = X, label = Y) model = xgb.train(data = dtrain,

问题 Good Day, i have this form view/startseites/index.html.erb and i specified a methode in my people_controller, she doesnt go. I prepared some ghost code for understanding. I want to give the entries from dropdowns with the button_to tag to the controller action checkValid. There i want to validate the entries against the database. I have to read and write from and to the table. I hope its clearly enough. class PeopleController < ApplicationController def checkValid @trainerName = params[

问题 After many sites searched and googling, I can't find anything for my problem. I want to capture the sequence of user interactions on android device. Starting from when the device is powered ON. And one more thing is that I'm not talking about the user event on UI of any application. It's for whole device UI interactions. And if any tools are available then please let me know about it. I didn't get anything about this. Any help or suggestion is well appreciate. 回答1: This is not possible,
