1. ### Which statistical test?

Which test can I use for analyzing the effect of a categorical independent variable, such as preoperative ASA score (1/2/3/4), on a binary dependent variable, such as postoperative complication (yes/no)? I know that the chi squared test is an option, but this test does not tell me if the...
2. ### Association/ correlation binary and continuous data non-normal distribution

Hi, I want to perform an association analysis between a binary (dichotomous?) variable and continuous variable. The binary variable is whether something is present or not, "Yes" or "No"/ "1" or "0" .... etc. The continuous variable are numbers between ~150 and 170~. The continuous variable is...
3. ### Multivariate repeated measures, binary and continuous

Hello all. I am working with a data set of multivariate repeated measurements. Specifically, subjects performed an exercise they were taught up to three times each and recorded heart rate variability (HRV) and whether they felt a particular sensation (details omitted). Whether they reported...
4. ### Getting values larger than 1 for a logit test?

I have run a logit test on a binary dependent variable "gambled?" against "Age" in STATA. I have the dependent variable coded as 0 for no and 1 for yes. However I have a coefficient of 1.54 on the independent variable "Age". How can this be in a logistic regression that is meant to be between 0...
5. ### Correlation between Binary (presence/absence)and Continuous Data

Thanks for the help in advance! I have a binary variable (1 or 0) that describes if a species is present or absent in an area. I also have a list of various crop acreages (continuous variable). I want to correlate the two to see if a certain crops acreage is correlated to the species...
6. ### Binary Logistic Regression Output missing some Sig values

I am running a Binary Logistic Regression on: - A numeric Fixed Factor as the dependent variable (two levels) - 3 numeric Fixed Factors as independent variables (two levels each) - 6 numeric Covariates as independent variables On my output, the Likelihood Ratio Tests table gives me...

### Factor analysis, what type of data can I use?

Hello everyone, I have a social science dataset composed of circa 40 variables. The data types I am using are quite diverse. The variables I am using (briefly put) are: are age, gender, educational background(1-7 scale), 7 point perception scales measuring the degree of trust in...
9. ### Binary Logistic Regression with categorical predictors and interactions.

I'm new to logistic regression and the project I'm working on requires a model that involves two predictors: Experimental condition (categorical variable with 8 categories) Score on a measure (continuous variable) So, one categorical predictor and one continuous predictor. But, these two...
10. ### finding correlations

It has been a while since I have taken statistics. I used to know it pretty well but now sadly it has been lost. I'm looking for help in finding correlations between two things. The tricky part is that I don't necessarily have numbers to go by. I'll give you an example. I want to know if a...
11. ### GARCH fitting to binary data / latent data

Dear all I am trying to fit a simple ARCH(1)/GARCH(1,1) model to a set of binary data, i.e. I assume a latent GARCH process that is only observed at the values a and b, say (whenever it crosses or hits those thresholds). I found some ideas on fitting a censored GARCH (by SX Wei, for example...
12. ### Correlate a continuous with a binary variable

Hey everyone. I have a simple problem and was hoping to get your advice with. I am trying to correlate a continuous variable with a binary one. Let's say the binary variable represents a Yes/No option and the continuous just a number between 1-100. How should I go about doing that? I...
13. ### Nonlinear Panel Regression in R

Hello World. I have a micro data set for my local CPI basket structured as (panel data with varying monthly periods over set products) in Eviews. I however, need to run a Logit model on a number of covariates which include a set of dummies. Eviews is limited in this regard (in that it cannot...
14. ### Q re Kappa statistic

I am trying to calculate inter-rater reliability scores for 10 survey questions-- most of which are binary (yes/no). The agreemeant level bettwen the two raters is 70-90% on nearly every question, however the Kappa score is often very poor (0.2- 0.4). Can this be right? Secondly, can you...
15. ### Problem with mixed effects model with binary data

Hi guys, I have a question about logit mixed effects model. I tried to use lmer to fit a model with binary dependent variable (Yes or No), a categorical fixed predictor with 3 levels, and two random effects. However, it turned out that one level of the fixed resulted in only positive outcomes...
