DAX query is used in Power BI to retrieve and manipulate data from datasets.
DAX stands for Data Analysis Expressions
Used to create calculated columns, measures, and tables
Can perform calculations, filtering, and aggregation on data
Examples: CALCULATE, SUMX, FILTER
Logistic regression is a statistical model used to predict the probability of a binary outcome based on one or more predictor variables.
Logistic regression is used when the dependent variable is binary (0/1, True/False, Yes/No, etc.)
It estimates the probability that a given observation belongs to a particular category.
The output of logistic regression is a probability score between 0 and 1.
It uses the logistic fun...
Construct 4 Array Tree and implement operations
Create an array to represent the tree structure
Implement operations like insert, delete, search, and traversal
Example: Construct a binary search tree using arrays
Use hashing to compare the JSON files in O(1) time complexity.
Create a hash function to convert the JSON data into a unique hash value.
Calculate the hash value for each JSON file and compare the hash values.
If the hash values are equal, the JSON files are identical.
Example: Use MD5 or SHA-256 hash functions for generating hash values.
Use array indices to map parent to children in a 4 Array tree in O(1) space complexity.
Assign children of a parent at indices 4*i+1, 4*i+2, 4*i+3, 4*i+4 where i is the index of the parent.
To find parent of a child at index j, use (j-1)/4 to get the parent index.
Total nodes in a binary tree can be found using depth-first or breadth-first traversal algorithms with time complexity O(n) and space complexity O(h), where h is the height of the tree.
Use depth-first traversal (pre-order, in-order, post-order) or breadth-first traversal to visit each node and count the total nodes.
Time complexity is O(n) where n is the number of nodes in the tree.
Space complexity is O(h) where h ...
Type I errors are false positives; Type II errors are false negatives in hypothesis testing.
Type I Error (False Positive): Rejecting a true null hypothesis. Example: A test indicates a disease is present when it is not.
Type II Error (False Negative): Failing to reject a false null hypothesis. Example: A test fails to detect a disease that is present.
In statistical terms, Type I error is denoted by alpha (α), while...
Creating a credit risk model involves data collection, preprocessing, model development, validation, and implementation.
1. Data Collection: Gather historical data on borrowers, including credit scores, income, and repayment history.
2. Data Preprocessing: Clean and preprocess data to handle missing values, outliers, and categorical variables.
3. Feature Engineering: Create relevant features that may impact credit ri...
SQL join is used to combine rows from two or more tables based on a related column, while the HAVING clause is used to filter groups based on a specified condition.
SQL join is used to retrieve data from multiple tables based on a related column
Types of SQL joins include INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL JOIN
HAVING clause is used with GROUP BY to filter groups based on a specified condition
Example: SELECT...
Analyzing a bank's balance sheet involves examining key ratios such as capital adequacy, asset quality, and liquidity.
Calculate capital adequacy ratio (CAR) to assess the bank's ability to absorb losses
Examine asset quality by calculating non-performing asset (NPA) ratio
Analyze liquidity by calculating loan-to-deposit (LTD) ratio
Assess profitability by calculating return on assets (ROA) and return on equity (ROE) ...
