R: Can I analyze non-varying-across-individual alternative-specific attribute variables with mlogit?

问题 I'm new to discrete choice modeling, so my apologies if I am misunderstanding a fundamental aspect of the analysis. I would like to run a discrete choice analysis with an individual-specific variable and what I think are alternative-specific attribute variables. From the mlogit vignette I think the individual-specific variable is a "choice situation specific covariate" (in the new vignette) and the alternative-specific attribute variables are "alternative specific covariates with generic

问题 I have a batch script which founds which drive is carrying my folder (diskpart situation) and founding folder, then it lists the text files (for now its text) in that folder. Anyways the problem is while the batch is asking me to choose which one do i want to open, it works until 9. I can't even press 10 because when i press 1 it automatically opens the text file. How can i write 2 digit numbers? Because the folder always will change and the might be 30 choices. Here's my code; @for %%a in (

Attribute error when generating random numbers in Python

问题 I asked a similar question regarding this same piece of code earlier but once again I have found myself stuck. Particularly on the generation of a license plate containing two letters, two numbers, and then two letters. I hope that this question isn't a duplicate but in this circumstance I am very stuck with what to do, this is the code so far and I hope you can identify where I am going wrong: from datetime import date, datetime, time, timedelta import time, string from random import uniform
