如何从statsmodels olsWLS回归2D参数测试得到的prediction

来源：蜘蛛抓取(WebSpider) 时间：2017-08-11 05:55 标签： statsmodels 逻辑回归
The code that I'm writing has two classes: writeInts and readInts. I wrote writeInts to randomly generate 100 numbers between 0 and 1000 and output them to a data.dat file.
readInts is supposed to open a DataInputStream object and read in the "raw" data from the data.dat file and store the 100 integers in an array. My problem is that I can't seem to read the data correctly. Any help with this would be greatly appreciated. Thanks!
writeInts:
import java.io.*;
public class WriteInts {
public static void main(String[] args) throws IOException {
DataOutputStream output = new DataOutputStream(new FileOutputStream("data.dat"));
int num = 0 + (int)(Math.random());
int[] counts = new int[100];
for(int i=0; i&100; i++) {
output.writeInt(num);
counts[i] +=
System.out.println(num);
output.close();
import java.io.*;
import java.util.*;
public class ReadInts {
public static void main(String[] args) throws IOException {
// call the file to read
Scanner scanner = new Scanner(new File("data.dat"));
int[] data = new int[100];
int i = 0;
while (scanner.hasNextInt()) {
data[i++] = scanner.nextInt();
System.out.println(data[i]);
scanner.close();
解决方案 If you want to write binary data, use DataInputStream/DataOutputStream. Scanner is for text data and you can't mix it.
WriteInts:
import java.io.*;
public class WriteInts {
public static void main(String[] args) throws IOException {
DataOutputStream output = new DataOutputStream(new FileOutputStream(
"data.dat"));
for (int i = 0; i & 100; i++) {
output.writeInt(i);
System.out.println(i);
output.close();
import java.io.DataInputS
import java.io.FileInputS
import java.io.IOE
public class ReadInts {
public static void main(String[] args) throws IOException {
DataInputStream input = new DataInputStream(new FileInputStream(
"data.dat"));
while (input.available() & 0) {
int x = input.readInt();
System.out.println(x);
input.close();

在code，我正在写有两类：writeInts和readInts。我写writeInts随机生成0和1000，并将其输出之间100号到Data.dat文件。 readInts应该打开一个DataInputStream的对象，并在从Data.dat文件的“原始”数据读和100的整数存储在数组中。我的问题是，我似乎无法正确读取数据。任何帮助，这将大大AP preciated。谢谢！ writeInts： 进口java.io. *;公共类WriteInts {
公共静态无效的主要（字串[] args）抛出IOException
DataOutputStream类输出=新的DataOutputStream类（新的FileOutputStream（“data.dat文件”））;
INT NUM = 0 +（int）的（的Math.random（））;
INT [] =计数INT新[100];
的for（int i = 0; I＆LT; 100;我++）{
output.writeInt（NUM）;
计数[I] + = NUM;
的System.out.println（NUM）;
output.close（）;
readInts： 进口java.io. *;进口的java.util。*;公共类ReadInts {
公共静态无效的主要（字串[] args）抛出IOException
//调用文件阅读
扫描仪扫描=新的扫描仪（新的文件（“data.dat文件”））;
INT []数据= INT新[100];
INT I = 0;
而（scanner.hasNextInt（））{
数据[我++] = scanner.nextInt（）;
的System.out.println（数据由[i]）;
scanner.close（）;
}} 解决方案 如果你想要写的二进制数据，使用的 DataInputStream所/ DataOutputStream类的。 扫描仪的是文字数据并不能混用。 WriteInts： 进口java.io. *;公共类WriteInts {
公共静态无效的主要（字串[] args）抛出IOException
DataOutputStream类输出=新的DataOutputStream类（新的FileOutputStream（
“data.dat文件”））;
的for（int i = 0; I＆LT; 100;我++）{
output.writeInt（ⅰ）;
的System.out.println（ⅰ）;
output.close（）;
ReadInts： 进口java.io.DataInputStream中;进口java.io.FileInputStream中;进口java.io.IOException异常;公共类ReadInts {
公共静态无效的主要（字串[] args）抛出IOException
DataInputStream以输入=新DataInputStream所（新的FileInputStream（
“data.dat文件”））;
而（input.available（）大于0）{
INT X = input.readInt（）;
的System.out.println（X）;
input.close（）;
