The Logistic regression is a linear model used for binomial regression. It is used in medical science and to predict a customer’s tendency to purchase a product. It makes use of predictor variables for this purpose.Logistic Regression allows easier analysis of results in the form of odds ratios and statistical hypothesis testing.A generalized linear model has taken input for a non-linear link function. The linear model has the following form −z = c1x1 + c2x2 + … cnxn + i = ct x + iHere,c is the coefficient vector, i is the intercept value x is the observation vector

Use the Contains() method to check if a string contains a word or not.Set the string −string s = "Together we can do so much!";Now let’s say you need to find the word “much”if (s.Contains("much") == true) {    Console.WriteLine("Word found!"); }Let us see the complete code −Example Live Demousing System; public class Demo {    public static void Main() {       string s = "Together we can do so much!";       if (s.Contains("much") == true) {          Console.WriteLine("Word found!");       } else {          Console.WriteLine("Word not found!");       }    } }OutputWord found!

Use the Equals method to check if an item exists in a C# array.Set string and substring −string subStr = "pqrs"; string[] str = {    "abcd",    "ijkl",    "pqrs",    "wxyz" };Now check whether the substring is part of the string or not using the Equals method.if (item.Equals(subStr)) {    Console.WriteLine("Item Found"); }Here is the complete code −Example Live Demousing System; namespace Program {    public class Demo {       public static void Main(String[] args) {          string subStr = "pqrs";          string[] str = {             "abcd",             "ijkl",             "pqrs",             "wxyz"          };          foreach(string item in str) {             if (item.Equals(subStr)) {                Console.WriteLine("Item Found");             }          }       }    } }OutputItem Found

To get the maximum occurred character in a string, loop until the length of the given string and find the occurrence.With that, set a new array to calculate −for (int i = 0; i < s.Length; i++)    a[s[i]]++; }The values we used above −String s = "livelife!"; int[] a = new int[maxCHARS];Now display the character and the occurrence −for (int i = 0; i < maxCHARS; i++)    if (a[i] > 1) {       Console.WriteLine("Character " + (char) i);       Console.WriteLine("Occurrence = " + a[i] + " times");    }Let us see the complete code ...

To display multiple blank lines, we will take a while loop.Here, we are printing 10 blank lines using Console.WriteLine();while (a < 10) {    Console.WriteLine(" ");    a++; }The following is the complete code to display multiple blank lines −Exampleusing System; namespace Program {    public class Demo {       public static void Main(String[] args) {          int a = 0;          while (a < 10) {             Console.WriteLine(" ");             a++;          }          Console.WriteLine("Displayed 10 blank lines above!");          Console.ReadLine();       }    } }

To display a line, Console.Write() is used in C#.Console displays the result on the console. I have first set a string.string str = "Tom Hanks is an actor";Now displaying the above line.Console.WriteLine(str);The following is the complete code −Example Live Demousing System; namespace Program {    public class Demo {       public static void Main(String[] args) {          string str = "Tom Hanks is an actor";          Console.WriteLine("Displaying a line below");          Console.WriteLine(str);          Console.ReadLine();       }    } }OutputDisplaying a line below Tom Hanks is an actor

With C#, you can easily display the following diamond shape.$ $$$ $$$$$ $$$$$$$ $$$$$$$$$ $$$$$$$ $$$$$ $$$ $To display a diamond shape, you need to focus on the following points −Number of rows Dollar sign to be displayed Empty spacesConsidering the above you can easily create the diamond shape as shown in the below code −Example Live Demousing System; namespace Program {    public class Demo {       public static void Main(String[] args) {          int i, j, r, d, e;          // rows = 5          r = 5;          // display dollar sign          d = 1;          // empty space          e = r - 1;          for (i = 1; i < r * 2; i++) {             // display empty space             for (j = 1; j

Binary triangle is formed with 0s and 1s. To create one, you need to work around a nestes for loop and display 0s and 1s till the row entered.for (int i = 1; i

To display a line in C#, use the Console.WriteLine().Under that set a blank line −Console.WriteLine(" ");The following is the code that displays a blank line −Example Live Demousing System; namespace Program {    public class Demo {       public static void Main(String[] args) {          Console.WriteLine(" ");          Console.WriteLine("Displayed a blank line above!");          Console.ReadLine();       }    } }OutputDisplayed a blank line above!

To find the difference between two dates in C#, you need to first set two dates to be compared using the DateTime object. We will use the DateTime class in C#.Date 1DateTime date1 = new DateTime(2018, 09, 15); Console.WriteLine("Date 1 : {0}", date1);Date 2DateTime date2 = new DateTime(2018, 09, 28); Console.WriteLine("Date 2 : {0}", date2);Now let us compare both the dates in C#. The following is an example to compare dates in C#.Example Live Demousing System; namespace Program {    class Demo {       static int Main() {          DateTime date1 = new DateTime(2018, 09, 15); ...
