1. ### Looking for feedback on application of chi-square test

I am a cost engineer working in the building construction field. I am seeking some advice/feedback on the use of a chi-square test for assessing how well a cost estimate follows an expected distribution. Our organization has developed an empirical collection of the distribution of building...
2. ### Sample size estimation for multinomial autocorrelated data

I'm trying to work out the minimum sample size needed to accurately characterise land cover data. The idea is to set out the a number of quadrats across the study site and identify what land cover type occurs in each. I have an idea as to how many categories there should be. So this is a...
3. ### Multinomial probabilty

Hi, Could anyone suggest what test should I apply in the case I have probabilities of 0. For example, I have a vector of counts 127,2,1,0 and I want to test if this vector fits one of the following probabilities (for example) p1=1,0,0,0 ; p2=0.75,0.25,0,0; p3=0.5,0.25,0.25,0 At first I...
4. ### Statistical Analysis for Master's Thesis

Hello Everyone, So this is my first forum post ever :) probably because I just couldn't figure out solution by myself this time. Thank you in advance for your suggestions and help! So I have done previous STATS projects and surveys, but my options (for the responses) were usually Yes/No or...
5. ### How to interpret this multinomial logistic regression result?

I done a multinomial logistic regressie for influence of income on voting right or left. Right-left is coded as a continuous as =0 extreme right and 10 extreme left And income = 1.hard to very hard to cope with income 2. can cope with it and 3. can...
6. ### Guidance appreciated: Multinomial mixed data types population characterization

Guidance appreciated: I have approx 40k records from about 50 colleges. Data is FERPA-compliant one student per record, with age (integer), gender, ethnicity, college, course, and section. Course is selected from a set of size three. I need some guidance on how to characterize this population...
7. ### multinomial distribution and degrees of freedom

Hi I have some data from a housing survey (sample size 13,500) and have found that the proportion of privately rented housing is slightly higher than the proportion of social housing. i want to test if the proportions are different. I found some advice at the link below indicating that I must...
8. ### [Multinomial Distribution] Help with applying Multinomial to a biological problem

Hello all, I need help with a stats question I'm trying to solve for a biological question. http://en.wikipedia.org/wiki/Multinomial_distribution. Say you have a town and each street on it will have a different number of bins. In each bin you will find a different number of baseballs, most...
9. ### MLE of multinomial distribution with missing values

Hi, I am trying to solve a problem and the results I get seem counter-intuitive. We randomly throw n balls into an area partitioned into 3 bins b_1,b_2,b_3. The size of each bins is proportional to the probability the ball will fall in it. Let's call these probabilities p_1,p_2,p_3. This...
10. ### mlogit from STATA to R

I know R fairly well but have very little experience with STATA. I am trying to convert the below mlogit command so it is usable in R. Can anyone help me? mlogit conflict lc1 lc2 ltsc0 ltsc1 ltsc2 loi loic1 loic2 lois0 let letc1 letc2 lets0 lli limc1 limc2 lims0 lyo lyoc1 lyoc2 lyos0 llpo lpoc1...
