我想编写用于绘制逻辑回归模型的代码,即"S"形逻辑曲线.怎么可以这样做,因为我有两个独立的协变量？我正在附加我的数据集和我的模型的代码.先感谢您.

# logostic regression
dat$gender <- factor(dat$gender)
mylogit<- glm(gender~press+v,data=dat,family="binomial")

Handler类发生了什么事.为什么它向我展示这种类型的错误？我可以通过调用Handler覆盖方法来解决它.但我不想要他们.我该怎么办.

public class MainActivity extends Activity {


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    blink();

}

private void blink(){
    final Handler handler = new Handler(); //showing error and need to call their override methods. 
    new Thread(new Runnable() {
        @Override
        public void run() {
            int timeToBlink = 1000;    //in milissegunds
            try{Thread.sleep(timeToBlink);}catch (Exception e) {}
            handler.post(new Runnable() {
                @Override
                public void run() {
                    TextView txt = (TextView) findViewById(R.id.blink);
                    if(txt.getVisibility() == View.VISIBLE){
                        txt.setVisibility(View.INVISIBLE);
                    }else{
                        txt.setVisibility(View.VISIBLE);
                    }
                    blink();
                }
            });
        }
    }).start();
} …
